Abstract

We report on the study of a new liquid scintillator target for neutrino interactions in the framework of the research and development program of the Borexino solar neutrino experiment. The scintillator consists of 1,2-dimethyl-4-(1-phenylethyl)-benzene (phenyl-o-xylylethane, PXE) as solvent and 1,4-diphenylbenzene (para-Terphenyl, p-Tp) as primary and 1,4-bis(2-methylstyryl)benzene (bis-MSB) as secondary solute. The density close to that of water and the high flash point makes it an attractive option for large scintillation detectors in general. The study focused on optical properties, radioactive trace impurities and novel purification techniques of the scintillator. Attenuation lengths of the scintillator mixture of 12 m at 430 nm were achieved after purification with an alumina column. A radiocarbon isotopic ratio of C 14 / C 12 = 9.1 × 10 - 18 has been measured in the scintillator. Initial trace impurities, e.g. 238U at 3.2 × 10 - 14 g / g could be purified to levels below 1 × 10 - 17 g / g by silica gel solid column purification.

Abstract

The results of background measurements with the second version of the BOREXINO Counting Test Facility (CTF-II), installed in the Gran Sasso Underground Laboratory, were used to obtain limits on the instability of nucleons, bounded in nuclei, for decays into invisible channels ($inv$): disappearance, decays to neutrinos, etc. The approach consisted of a search for decays of unstable nuclides resulting from $N$ and $NN$ decays of parents $^{12}$C, $^{13}$C and $^{16}$O nuclei in the liquid scintillator and the water shield of the CTF. Due to the extremely low background and the large mass (4.2 ton) of the CTF detector, the most stringent (or competitive) up-to-date experimental bounds have been established: $��(n \to inv) > 1.8 \cdot 10^{25}$ y, $��(p \to inv) > 1.1 \cdot 10^{26}$ y, $��(nn \to inv) > 4.9 \cdot 10^{25}$ y and $��(pp \to inv) > 5.0 \cdot 10^{25}$ y, all at 90% C.L., 22 pages, 3 figures,submitted to Phys.Lett.

Abstract

(60)Cu and (64)Cu are useful radioisotopes for positron emission tomography (PET) radiopharmaceuticals and may be used for the preparation of promising agents for diagnosis and radiotherapy. In this study, the production and purification of (60/64)Cu starting from (60/64)Ni using a new automated system, namely Alceo, is described. A dynamic process for electrodeposition and dissolution of (60/64)Ni/(60/64)Cu was developed. Preliminary production yields of (60)Cu and (64)Cu were 400 and 300mCi, respectively. (64)Cu was used to radiolabel the hypoxia detection tracer ATSM with a specific activity of 2.2+/-1.3Ci/micromol.

Abstract

BOREXINO, a real-time device for low energy neutrino spectroscopy is nearing completion of construction in the underground laboratories at Gran Sasso, Italy (LNGS). The experiment's goal is the direct measurement of the flux of 7Be solar neutrinos of all flavors via neutrino-electron scattering in an ultra-pure scintillation liquid. Seeded by a series of innovations which were brought to fruition by large scale operation of a 4-ton test detector at LNGS, a new technology has been developed for BOREXINO. It enables sub-MeV solar neutrino spectroscopy for the first time. This paper describes the design of BOREXINO, the various facilities essential to its operation, its spectroscopic and background suppression capabilities and a prognosis of the impact of its results towards resolving the solar neutrino problem. BOREXINO will also address several other frontier questions in particle physics, astrophysics and geophysics.

Abstract

The results of background measurements with the prototype of the Borexino detector (CTF) have been used to obtain an upper bound on the neutrino magnetic moment, μ ν . The new upper limit for μ ν from pp and 7 Be solar neutrinos is (5.5×10 −10 ) μ B (90% c.l.) in the Standard Solar Model scenario. This is the first limit on μ ν obtained using sub-MeV neutrinos. The sensitivity of the prototype to the neutrino charge radius and the neutrino radiative decay are also presented.

Abstract

If heavy neutrinos with mass $$\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\smile}$}}{l} $$ are emitted in the decays of 8B in the Sun, then νH→νL+e ++e − decays should be observed. In the present work, the results of background measurements with the Borexino Counting Test Facility have been used to obtain bounds on the number of these decays. As a result, new limits on the coupling |U eH|2of a massive neutrino in the range of 1.1 MeV to 12 MeV have been derived (|U eH|2≤10−3−10−5). The obtained limits on the mixing parameter are stronger than obtained in previous experiments using nuclear reactors and accelerators.

Abstract

BOREXINO, a real-time device for low energy neutrino spectroscopy is nearing completion of construction in the underground laboratories at Gran Sasso, Italy (LNGS). The experiment's goal is the direct measurement of the flux of 7Be solar neutrinos of all flavors via neutrino-electron scattering in an ultra-pure scintillation liquid. Seeded by a series of innovations which were brought to fruition by large scale operation of a 4-ton test detector at LNGS, a new technology has been developed for BOREXINO. It enables sub-MeV solar neutrino spectroscopy for the first time. This paper describes the design of BOREXINO, the various facilities essential to its operation, its spectroscopic and background suppression capabilities and a prognosis of the impact of its results towards resolving the solar neutrino problem. BOREXINO will also address several other frontier questions in particle physics, astrophysics and geophysics.

Abstract

A large volume (4.8 m3) liquid scintillator detector has been running in Hall C of the Gran Sasso Underground Laboratory since February 1995. This detector is called the “Counting Test Facility” (CTF). The main goal of the detector facility is the measurement of ultralow background levels in scintillators and the development of processes able to purify them at this level. The detector has been designed to have exceptional sensitivity using a variety of methods to identify backgrounds. With the CTF, records were achieved in the domain of low background large volume detectors. Limits of 3.5 ± 1.3 × 10−16 g/g and 4.4−1.2+1.5 × 10−16 g/g for the 238U and 232Th daughters, respectively, and 1.85 ± 0.13 ± 0.01 × 10−18 for the isotopic abundance of 14C relative to 12C were obtained. These results are very encouraging and point towards the feasibility of low energy, real time scintillation detectors for solar neutrinos, such as Borexino.

Abstract

A new head holder for the fixation and repositioning of the patient head in PET, CT, and MR scanners has been designed and tested. With this device, a bidimensional correlation between functional and anatomical brain images can also be obtained. Head fixation and repositioning are achieved using the patient's dental morphology as an anatomical reference. With a dentistic material, a mold of the patient's teeth is obtained in a few minutes. The molding substance rests on a plastic support, fixed to the head holder. Each time the patient undergoes a new study, his/her personal mold is used, ensuring accurate head repositioning. External markers fixed on the head holder (made visible in lateral PET and CT projection images, midsaggital MR images, and also on the axial images) make it possible to record and recognize the angular orientation and the position of the brain in the three-dimensional space, to correlate images of the same patient obtained with different neuroimaging modalities, and to accurately reposition patients for follow-up studies. The head holder was tested on several subjects. Fixation and repositioning accuracy of within 2.5 mm were achieved in the three-dimensional space. Orientation accuracy was 1 degree.
