In the framework of the HERA Luminosity Upgrade Project it is foreseen to move the final focus quadrupole magnets of the proton machine 16 m closer to the interaction region. As the electrons must not be affected by these magnets, the beam pipes for electrons and protons have to be well separated at these magnets. This implies rather sharp bends with bending radii down to 360 m for the electron orbit in the interaction region. At an electron energy of 30 GeV and a beam current of 58 mA these bends cause a high level of synchrotron radiation. The synchrotron radiation will be guided through the interaction region and will be absorbed far downstream at low power densities. However, it is unavoidable to stop parts of the synchrotron radiation beam at high linear power densities of up to 2 kW/cm rather close to the interaction point where the electron and proton vacuum systems are separated. In order to protect the proton final focus magnet and the septum beam pipe from this synchrotron radiation, a high power synchrotron radiation absorber was designed. This absorber not only has to withstand the heat load of the synchrotron radiation, but it also has to be designed to minimize the backward scattering of the radiation, because these scattered photons might hit sensitive detector components in the interaction region. This paper will first give an overview of the geometry of the interaction region with special emphasis on the synchrotron radiation. Then the geometrical and thermal requirements for the high power absorber will be described and finally the layout of the absorber will be presented.

Inactivation of the TSG101 gene was recently shown to induce malignant transformation of NIH/3T3 fibroblasts. Abnormal TSG101 transcription profiles were observed in various human cancers, and large intragenic deletions of the TSG101 gene were reported for a series of human breast cancer specimens, pointing to a potential tumor-suppressive activity of TSG101. However, subsequent more detailed studies on a large panel of breast carcinoma samples did not confirm the tumor-associated genomic deletions. Here we analyzed the transcription patterns of the TSG101 gene in soft-tissue sarcomas and non-neoplastic human tissues. Forty-five of 71 soft tissue sarcoma samples (63%) displayed variant transcripts; however, identical aberrant transcripts were also detected in seven of 15 non-neoplastic control tissues. Restriction fragment length polymorphism analysis of the TSG101 gene excluded major genomic rearrangements in the soft tissue sarcoma samples. Northern blot analysis revealed a very low abundance of variant transcripts as compared with the wild-type TSG101 transcript. These data point to aberrant splicing of the TSG101 mRNA in normal and transformed human mesenchymal tissues rather than tumor specific alterations of the TSG101 gene. In summary, this analyses does not support a pathogenic role for altered TSG101 expression in human soft tissue sarcomas.

In myxoid and round cell liposarcomas, a specific chromosomal translocation [(12;16)(q13;p11)] results in the expression of chimeric fusion transcripts encompassing parts of the FUS gene (16p11) at their 5' ends and the CHOP gene (12q13) at their 3' ends. Using a reverse transcription-PCR protocol, we determined the prevalence of FUS-CHOP fusion transcripts in a series of liposarcoma samples. Fusion transcripts were detected in 13 of 30 biopsy samples from soft tissue liposarcomas. Expression of fusion transcripts was not restricted to myxoid and round cell liposarcomas, as suggested previously; it was also detected in 1 of 3 well-differentiated and 4 of 14 pleomorphic liposarcomas. Sequence analysis revealed four different FUS-CHOP fusion transcript variants, two of which have not been described before. Furthermore, using FUS-CHOP fusion transcripts as targets in reverse transcription-PCR assays, we detected disseminated tumor cells in peripheral blood or bone marrow in 3 of 5 patients undergoing surgery for soft tissue liposarcoma.

The majority of patients with colorectal cancer present at a stage when the primary cancer can be resected with curative intent. However, despite the high resectability rate, about 30-50% of these patients subsequently develop metastatic disease. In these patients, neoplastic cells were disseminated either before or during surgery of the primary cancer. Due to the lack of appropriate detection systems, the extent of pre- and intraoperative hematogenic tumor cell dissemination has not yet been determined. Using a reverse transcription-PCR assay to amplify cytokeratin 20 transcripts, we were able to detect 10 colorectal cancer cells in 10 ml of blood. Blood samples were taken from 65 patients undergoing resection of primary colorectal cancer or liver metastasis of colorectal cancer pre-, intra-, and postoperatively. Circulating tumor cells were detected in 24 of 58 patients with colorectal resections in correlation to the tumor stage and in 6 of 7 patients who underwent hemihepatectomy for liver metastasis. In 8 of 58 patients with colorectal resection and in 5 of 7 patients with hemihepatectomy, tumor cells could only be detected during or during and after surgery. These results demonstrate that hematogenic tumor cell dissemination is a frequent and early event in colorectal cancer. Surgery enhances the release of tumor cells into the circulation. The long-term follow-up of our patient cohort will provide data on the prognostic relevance of circulating tumor cells and might lead to new therapeutic concepts for perioperative prophylaxis of tumor cell implantation or postoperative adjuvant therapy regimens.

Gastrointestinale Stromatumoren (GIST) sind selten. Ihre maligne Variante stellt nur 3 Prozent aller gastrointestinalen Malignome dar. Haufigste Tumorlokalisation sind Magen und Dunndarm. Tumoren im Colon sind selten, der etwas haufigere Nachweis asymptomatischer Tumoren im Rektum kann mit dem leichten Zugang erklart werden. Die pra- oder intraoperative Differenzierung der Dignitat ist schwierig. Die Behandlung erfordert die vollstandige Tumorentfernung mit 2 cm Sicherheitsabstand ohne systematische Lymphadenektomie. Als prognostischer Faktor fur maligne GIST wurde das Grading identifiziert. Das 5-Jahresuberleben von 46 Patienten betrug in unserer Erfahrung nach kurativer Operation 69 Prozent.

Karzinome und Lymphome konnen aufgrund einer erhohten Glykolyse mit einem radioaktiv markiertem Glukoseanalogon, der F18-Desoxyglukose (FDG), in der Positronen-Emissions-Tomographie (PET) dargestellt und biologisch charakterisiert werden [2, 5]. Bei Weichgewebesarkomen liegen uber derartige biologisch-funktionelle Untersuchungen mit FDG wenige Daten vor. Andere Radiotracer wurden nur in einzelnen Fallen untersucht [3, 4]. Wir untersuchten, inwieweit die Glykolyse, die Tumorperfusion und der Aminosauretransport von Weichgewebesarkomen durch die PET mit verschiedenen Radiotracern darstellbar ist und ob damit diese Tumorentitat biologisch-funktionell charakterisiert werden kann.

Von 271 Patienten, die wegen Sarkomen von 3/88 bis 6/96 behandelt wurden, wurden 17 Patienten, die aufgrund von Lebermetastasen operiert wurden, retrospektiv analysiert. Funfmal konnte eine kurative und viermal eine palliative Resektion erfolgen, 8 Patienten wurden explorativ laparotomiert. Alle Primartumoren waren im Rumpfbereich lokalisiert, histologisch dominierte das Leiomyosarkom (41%). 53% der Tumoren waren niedrig und 47% mittelgradig differenziert. Resektable Patienten uberlebten median 56 Monate versus 5 Monate bei alleiniger Exploration. Morbiditat und Mortalitat betrugen 22%/0% fur die Resektion und 25%/12,5% fur die Exploration. Eine Resektion von Lebermetastasen ist indiziert, wenn eine R0-Resektion moglich erscheint.

Das Verstandnis der Onkogenese von Weichteilsarkomen hat in den letzten Jahren erhebliche Fortschritte gemacht. Die zentrale Bedeutung der Zellzyklusregulation konnte durch die Beteiligung von unterschiedlichen Genen nachgewiesen werden, die sowohl Keimbahnmutationen (p53, RB), wie auch somatische Mutationen (p53, BCL2, MDM2) oder variante Expressionen in Weichteiltumoren aufweisen. Als Besonderheit unter den soliden Tumoren lassen sich in einem Teil der Weichteilsarkome stabile Chromosomentranslokationen mit resultierenden Fusionsgenen nachweisen, deren klinische Nutzung, insbesondere hinsichtlich einer spezifischen Therapie, in besonderem Mase verfolgt wird.

In a 34-year-old woman who underwent ultrasound investigation because of recurrent pyelonephritis a space-occupying lesion in the liver was an incidental finding. Computed tomography (CT) and magnetic resonance imaging (MRI) confirmed a tumour in segment I of the liver. The patient had been on contraceptives for 12 years. She had no symptoms.Laboratory tests, including tumour markers, were unremarkable. Diagnostic tests to exclude malignant tumour with metastases were negative (thyroid scintigraphy, mammography, coloscopy and gastroscopy). Further tests (ultrasound, coeliaco-mesentericography, hydro-CT and spiral CT, MRI) revealed a tumour, 5 x 4 x 4 cm, in segment I of the liver, most likely an adenoma. Surgical intervention was indicated by the size and questionable malignancy of the tumor.At operation a tumour was found which originated from the inferior vena cava (IVC) and displaced segment I of the liver. The tumour was resected and the venous wall reconstructed with a Goretex patch. Histological examination indicated a poorly differentiated leiomyosarcoma of the IVC. Adjuvant radiotherapy was undertaken postoperatively. There has been no evidence of recurrence after 10 months.Leiomyosarcoma of the IVC can be mistaken, both by ultrasound and tomographic diagnostic procedures, for a tumour in segment I of the liver, especially an adenoma. A leiomyosarcoma of the IVC should be included in the differential diagnosis of an hepatic tumour that lies close to segment I of the liver.

Surgery for symptomatic hyperparathyroidism remains the standard therapy. Asymptomatic primary hyperparathyroidism (pHPT) is being diagnosed with increasing frequency owing to broad serum testing. Indications for surgery in this setting are controversial. For evaluation of surgical safety we performed a retrospective analysis of our patients who were being operated on for asymptomatic pHPT. From January 1988 until August 1995, 243 patients were treated for pHPT and registered prospectively at our unit. Seventy-six patients were classified as asymptomatic. In all, 75% of the patients were female; the mean age was 62 years. In this group, 87% of the patients had cervical sonography in order to localize the adenoma. Highly selective venous catheterization was required in cervical reexplorations. Statistical analysis for potential prognostic factors for the clinical outcome was performed. Successful cervical exploration was possible in 71 patients (94.7%). With 4 patients remaining hypercalcemic, the rate of persistency was 5.2%. Localization procedures were correct in 58% for cervical ultrasound and 77% for selective venous catheterization. Postoperative morbidity included one permanent recurrent laryngeal nerve palsy and 2 patients with hemorrhage who were treated by reoperation. While one case of permanent hypoparathyroidism was well controlled by oral supplementation, 18 patients recovered from temporary hypoparathyroidism. No postoperative mortality occurred. Risk factor analysis revealed only cervical reexplorations for HPT to be associated with a higher morbidity (P = 0.02). Surgery for asymptomatic pHPT can be performed with reasonable safety. Cervical reexplorations in asymptomatic patients should be reserved for special indications. Apart from this small group, all patients should be evaluated for surgery.

Abdominal pain developed after a bulimic binge in a 19-year-old girl with anorexia nervosa. She had unsuccessfully tried to induce vomiting. Physical examination showed no clinical sign of peritonitis, although there was diffuse abdominal tenderness on pressure.There was leukopenia (2200 G/l) and a raised serum lactate level (58 mg/dl). No free air was seen on a plain film of the abdomen. Abdominal sonography revealed little free fluid subhepatically.Acute respiratory impairment during investigations required emergency intubation. As bronchoscopy revealed aspiration a bronchial lavage was performed. Under gastroscopic control gastric emptying was achieved through a large gastric tube. After early improvement the patient developed the full picture of sepsis. Ultrasonography and needle puncture having revealed purulent intraabdominal fluid, a laparotomy was performed, which showed necrosis of the anterior and posterior walls of the stomach with free perforation. The greater curvature was resected. The patient slowly recovered but a relaparotomy for a subphrenic abscess became necessary on the 10th postoperative day. A year later there was free food passage, but the anorexia nervosa was unchanged.A bulimic binge can become life-threatening if the stomach does not empty spontaneously. Surgical intervention is required, if the patient's condition does not improve despite gastric emptying.

Radical or wide excision is the treatment of choice for soft-tissue sarcomas (STS) of the extremities. Multimodality therapy made limb-sparing surgery possible. While external beam radiotherpy is well established in this setting, few data are available about intraoperative radiotherapy (IORT). We performed an analysis of 36 patients treated with IORT and external beam radiation following resection of STS of the extremities between 1991 and 1995. Only STS classified as UICC stage IIb, III or IV were included. Operative morbidity was 17%, 14% showed late complications. Within a mean follow-up of 24 months (min. 6), there was one local recurrence in 30 patients treated curatively. The 3-year survival rate of patients treated curatively was 75%; 3-year recurrence-free survival was 65%.

Sarcomas of the retroperitoneum are characterized by a high rate of local recurrence. External beam radiotherapy is known to improve local control after surgical therapy. To increase local dosage of radiotherapy without affection of sensitive structures we applied intraoperative radiotherapy (IORT) since 1991 in a dedicated operative unit. To compare morbidity and tumor control we used a partly historic control group of patients treated since 1988 for retroperitoneal soft tissue sarcoma. 25 patients with a mean age of 53 years were operated. Tumor histology was dominated by liposarcoma and leiomyosarcoma, UICC stage IIB (T2 G2 N0 M0) was present in 45% of cases. Distant metastasis were diagnosed in 19% at therapeutic intervention. Tumor free margins were achieved in 55% while 29% showed microscopic and 16% macroscopic tumor residues after surgical intervention. 11 patients received IORT with a mean of 18 Gy, eight of those patients were treated additionally with a mean of 40,4 Gy externally. There were no differences in distribution of known risk factors for recurrence in the group of patients treated with or without IORT. The analysis showed no difference for perioperative morbidity. Tolerance for IORT and additional external beam radiotherapy was good. Local tumor control tended to be improved by IORT (p = 0.082) while overall survival was not affected at a mean follow-up of 24 months.

Im Rahmen der operativen Therapie maligner Tumoren ist in vielen Fallen eine perioperative Fremdbluttransfusion notwendig. Neben der Infektionsubertragung durch Fremdblut besteht durch die immunsuppressive Wirkung einer Fremdbluttransfusion unter Umstanden ein negativer Einflus auf die Prognose [1]. Eine Moglichkeit zur Vermeidung von Fremdbluttransfusionen besteht in der perioperativen Eigenblutspende und wurde bisher in erster Linie bei orthopadischen und herzchirurgischen Elektiv-Eingriffen genutzt.

The physics programme and the design are described of a new collider for particle and nuclear physics, the Large Hadron Electron Collider (LHeC), in which a newly built electron beam of 60 GeV, to possibly 140 GeV, energy collides with the intense hadron beams of the LHC. Compared to the first ep collider, HERA, the kinematic range covered is extended by a factor of twenty in the negative four-momentum squared, Q^2, and in the inverse Bjorken x, while with the design luminosity of 1e33 cm-2 s-1 the LHeC is projected to exceed the integrated HERA luminosity by two orders of magnitude. The physics programme is devoted to an exploration of the energy frontier, complementing the LHC and its discovery potential for physics beyond the Standard Model with high precision deep inelastic scattering measurements. These are designed to investigate a variety of fundamental questions in strong and electroweak interactions. The LHeC thus continues the path of deep inelastic scattering (DIS) into unknown areas of physics and kinematics. The physics programme also includes electron-deuteron and electron-ion scattering in a (Q^2 1/x) range extended by four orders of magnitude as compared to previous lepton-nucleus DIS experiments for novel investigations of neutron's and nuclear structure, the initial conditions of Quark-Gluon Plasma formation and further quantum chromodynamic phenomena. The LHeC may be realised either as a ring-ring or as a linac-ring collider. Optics and beam dynamics studies are presented for both versions, along with technical design considerations on the interaction region, magnets including new dipole prototypes, cryogenics, RF, and further components. A design study is also presented of a detector suitable to perform high precision DIS measurements in a wide range of acceptance using state-of-the art detector technology, which is modular and of limited size enabling its fast installation. The detector includes tagging devices for electron, photon, proton and neutron detection near to the beam pipe. Civil engineering and installation studies are presented for the accelerator and the detector. The LHeC can be built within a decade and thus be operated while the LHC runs in its high-luminosity phase. It so represents a major opportunity for progress in particle physics exploiting the investment made in the LHC.

Nonlinear forces introduce a limit for stable betatron oscillation amplitudes of the particles of an accelerator beam. Beyond this limit, the particle amplitudes will grow until the wall of the beam pipe is reached and loss occurs. That is why the focussing and guide fields of accelerators are designed to be as linear as possible. On the other hand, a perfectly linear machine would not work. Nonlinear sextupole fields have to be installed in order to compensate chromatic effects1. This turns the linear lenses effectively into achromats. The impact of the nonlinearity of these sextupoles and corresponding performance limitations have to be tolerated. Thus in every large accelerator there is a limit for the amplitude of stable betatron oscillations. Chromaticity correcting sextupoles present a natural scale to determine limitations for additional nonlinearities which arise from imperfections of the magnetic guide and focussing fields. Unfortunately, the strength of these parasitic nonlinearities becomes comparable to or even larger than the chromaticity sextupoles if the synchrotrons become considerable larger than existing machines.

This paper summarizes the results of the working group on Lattice Design at the 1990 Berkeley conference on Beam Dynamics of high luminosity asymmetric collider rings. The goal of this group was to compare the various schemes and concepts in the B‐factory designs which was studied and investigated in various accelerator laboratories. The crucial aspect of the lattice design is the layout of the interaction region. (AIP)

The nuclear spin relaxation rate R has been studied in liquid alloys Pb1-CXC with X=Li, As, Ag, In, Sn, Sb, Te, Au, Tl and Bi at various concentrations C, and for X=In, Sb, Bi as a function of temperature T at C=0.5. The 47 mu s isomer 207mPo, for which the quadrupolar contribution to R, RQ, is dominant, was used as the probe nucleus; it was produced and aligned by the nuclear reaction 206Pb ( alpha , 3n) and the relaxation rate was measured by the perturbed angular distribution technique. For most of the alloys studied here the contribution to RQ due to density fluctuations, RQNN, dominates. Thus these data complement the earlier measurements by the authors of alloys where the concentration fluctuation contribution, RQCC, dominated. They confirm the earlier findings that the magnitude of RQ in alloys is essentially determined by the valence difference between the partner elements and that the long-range components of the interaction are decisive for quadrupolar relaxation (i.e. distances larger than the nearest-neighbour distance).

An experimental quantity sensitive to the time development of the distance between two atoms in a liquid alloy, is the quadrupolar nuclear spin relaxation rate RQ. The existing material for s-p-alloys shows a systematic occurrence of string enhancements of RQ if there is an attractive interaction among the partner elements in alloys. Using a model of associates for the alloy, it is possible to connect RQ rather directly with the lifetime of the associate. For In---Hg at 260 K as an example, 10?11 sec is obtained.

The magnetic part of the nuclear spin relaxation rate, RM, has been measured at constant T in liquid Tl1-cPbc, Tl1-cBic and Tl1-cAuc (c

Applying the method of perturbed angular distributions following the nuclear reaction $^{115}\mathrm{In}(\ensuremath{\alpha},2n)^{117}\mathrm{Sb}^{m}$, systematic measurements have been made of the nuclear-quadrupolar relaxation rate ${R}_{Q}$ for $^{117}\mathrm{Sb}^{m}$ probe nuclei in liquid alloys of In, as a function of various parameters: the dependence of the rate enhancement on the partner element is established in 14 equicomposition alloys with $\mathrm{I}b$, $\mathrm{II}b$, $\mathrm{II}a$, $\mathrm{IV}a$, and $\mathrm{V}a$ group elements. The composition dependence of the rate in the In-rich domain has been recorded for ${\mathrm{In}}_{C}{X}_{1\ensuremath{-}C}$, $X=\mathrm{A}\mathrm{u},\phantom{\rule{0ex}{0ex}}\mathrm{H}\mathrm{g},\phantom{\rule{0ex}{0ex}}\mathrm{A}\mathrm{s},\phantom{\rule{0ex}{0ex}}\mathrm{a}\mathrm{n}\mathrm{d}\phantom{\rule{0ex}{0ex}}\mathrm{B}\mathrm{i}$, and the temperature dependence of the rate is presented for ${\mathrm{In}}_{0.5}$${\mathrm{Bi}}_{0.5}$ and ${\mathrm{In}}_{0.5}$${\mathrm{Hg}}_{0.5}$. On the average we find a correlation of the rate enhancement to the valence difference between In and the partner element. The composition dependence confirms the characteristic deviation from a simple substitutional behavior described by a $C(1\ensuremath{-}C)$ rule which has been found in earlier NMR work. The temperature dependence of the rate in ${\mathrm{In}}_{0.5}{X}_{0.5}$ alloys with enhancement, can be parametrized by an Arrhenius law where the activation energy is roughly a linear function of the alloy melting temperature; the proportionality factor, however, is about one half the factor occuring in diffusion. These results are examined in the frame of the Sholl and Warren theory for quadrupolar relaxation which we extend to alloys in its general form in terms of partial-dynamical structure factors taking advantage of analogies in the formulation of electrical resistivity. It is concluded from an evaluation of the formulas based upon a hard-sphere model that quadrupolar relaxation must be governed by the long-wavelength part of the structure factors. More specifically quadrupolar relaxation seems to be sensitive to the wave-number interval between the thermodynamical limit and the main peak of the static-pair correlation function of the liquid, a region which is poorly explored by other experimental techniques.

After approval of the construction of the new separated function electron synchrotron, DESY II, in May 1983, the design and fabrication of all components was completed and the new machine fully installed during a four month winter shutdown from Nov. 84 until Feb. 85. The new machine will be tested in parallel with normal operation of the old 7 GeV synchrotron, DESY I, by using 200 MeV electrons injected from the upgraded Linac I. Provisional power supplies run the magnets up to 1 GeV. During a second shutdown in winter 85/86 it is planned to install full magnetand rf-power and to connect all beam transfer lines to PETRA and DORIS. DESY I will then be turned off and most of the components will be used to form a new proton synchrotron (DESY III) for the HERA e--p project. An updated parameter list and first results from the initial tests of DESY II will be presented.

The operation of the Fermilab BO low s insertion involves the coordinated control of the 4 strings of quadrupoles of the insertion itself along with several magnetic correction elements (20 dipoles for the closed orbit, 2 quad circuits for betatron tunes, 1 skew quad circuit for coupling, and 2 sextupole circuits for chromaticity). When the beam is stored at high energy, these elements must correct the errors induced by the strong superconducting quadrupoles of the insertion as the optics are smoothly changed from the fixed target configuration to the low s state. The techniques and control programs for these manipulations and initial tests using a single coasting beam are described.

An interactive program to help design accelerator lattices and lattice insertions is described. Present limitations and directions of future development are indicated.

A connection between thermodynamic data, concentration fluctuations at small wave numbers k and nuclear spin relaxation due to quadrupolar interaction in liquid binary metallic alloys is established by analysing experimental data on In 0.5 X 0.5 alloys.

The quadrupolar part of the nuclear spin re laxat ion rate RQ in l i qu id al loys shows large changes with a l loy partner, concentrat ion, or temperature. Using the Shell-Warren theory, these are traced back to changes of the instantaneous f luc tuat ion of the e l e c t r i c f i e l d gradient due to the spat i a l s t ructure in the a l loy . Reference in made to examples from the s-p,metals. The changes in cor re la t ion time may act in such a way as to enlarge even fur ther the changes in RQ induced by the structure.

New data for quadrupolar spin relaxation in liquid In Sn1-c and Inc Pb1-c alloys are presented. The composition dependence RQ(cc) shoes characte-ristic deviations from the c(1-c) behaviour as observed in other systems. The alloy enhancement of RQ supports the thermodynamic interpretation presented recently by the authors.

In the following report we give a survey of linear machine theory. Our investigations are restricted to coasting‐beam betatron motion but coupling is taken into account in a general way. The equations of motion for on‐ and off‐momentum particles are derived and written in canonical form. From the canonicity it follows that all transfer matrices are automatically symplectic. Eigenvector methods are introduced to study the stability behavior. To investigate the influence of coupling, generalized lattice functions are defined and canonical perturbation techniques are applied.

Transverse phase space trajectories can be measured by using the TEVATRON beam position monitor in the standard turn by turn operation mode if a coherent betratron oscillation is excited by a dipole kick. The measurement of phase space coordinates is influenced by incoherent and coherent synchrotron oscillations and incoherent betatron oscillations. In order to investigate phase space trajectories in detail, all these effects must be understood quantitatively and if possible the measured data must be corrected. In this report the measuring and correction procedures will be investigated and the first measurements will be discussed.
