Abstract

Experimental results and simulation models show that crystals might play a relevant role for the development of new generations of high-energy and high-intensity particle accelerators and might disclose innovative possibilities at existing ones. In this paper we describe the most advanced manufacturing techniques of crystals suitable for operations at ultra-high energy and ultra-high intensity particle accelerators, reporting as an example of potential applications the collimation of the particle beams circulating in the Large Hadron Collider at CERN, which will be upgraded through the addition of bent crystals in the frame of the High Luminosity Large Hadron Collider project.

Abstract

The UA9 experimental equipment was installed in the CERN-SPS in March '09 with the aim of investigating crystal assisted collimation in coasting mode. Its basic layout comprises silicon bent crystals acting as primary collimators mounted inside two vacuum vessels. A movable 60 cm long block of tungsten located downstream at about 90 degrees phase advance intercepts the deflected beam. Scintillators, Gas Electron Multiplier chambers and other beam loss monitors measure nuclear loss rates induced by the interaction of the beam halo in the crystal. Roman pots are installed in the path of the deflected particles and are equipped with a Medipix detector to reconstruct the transverse distribution of the impinging beam. Finally UA9 takes advantage of an LHC-collimator prototype installed close to the Roman pot to help in setting the beam conditions and to analyze the efficiency to deflect the beam. This paper describes in details the hardware installed to study the crystal collimation during 2010., Comment: 15pages, 11 figure, submitted to JINST

Abstract

A series of Silicon crystal undulator samples were produced based on the approach presented in PRL 90 (2003) 034801, with the periods of undulation from 0.1 mm to 1 mm, and the number of periods on the order of 10. The samples were characterized by X-rays, revealing the sine-like shape of the crystal lattice in the bulk. Next step in the characterization has been the channeling tests done with 70 GeV protons, where good channeling properties of the undulated Silicon lattice have been observed. The photon radiation tests of crystal undulators with high energy positrons are in progress on several locations: IHEP Protvino, LNF Frascati, and CERN SPS. The progress in the experimental activities and the predictions from detailed simulations are reported., Comment: Invited talk at the NATO ARW "Advanced Photon Sources and Their Application" (Nor Hamberd, Armenia August 29 – September 02, 2004)

Abstract

31st European Photovoltaic Solar Energy Conference and Exhibition; 1492-1493, The purpose of this work is to assess the performances of large size LSC devices which closely represent systems that can be employed in building integrated applications like roofs or windows. Although the great potentialities of LSC photovoltaic systems, up to now only a few real word applications exist and most of the scientific work about LSCs concerns only luminescent dyes and small size devices (generally 5cm×5 cm). The subjects of this study are LSC devices made of dye doped PMMA slabs with an area of 50cm×50cm and a thickness of 5mm: five different dyes with different colors (violet, gree, yellow, orange, red) have been tested.

Abstract

28th European Photovoltaic Solar Energy Conference and Exhibition; 636-639, New robust luminescent solar concentrators were produced by growing Eu(TTA)3phen -containing parylene thin films on PMMA slabs through a novel co- deposition process. The optical measurements demonstrated that Eu(TTA)3phen -containing parylene exhibits higher absorption than the conventional Eu(TTA)3phen films and the luminescence peaks characteristic of Eu(TTA)3phen compound. This indicates that the Eu complex is not affected by the matrix interaction thus maintaining its extremely large Stokes shift. Moreover the parylene matrix improves the luminescence intensity of the films: in fact, under the same absorption these films show a luminescence intensity more than two times higher than standard Eu(TTA)3phen ones. The current-voltage (I-V) measurements show that the Eu(TTA)3phen -containing parylene LSCs produce a current density more than twice as high as conventional Eu(TTA)3phen ones with the same Eu(TTA)3phen quantity and that their efficiency decreases more than ten times slower than organic-based LSCs at increasing illuminating area, thus highlighting the feasibility of developing large size LSCs.

Abstract

The radiation emitted by 180-GeV/c volume-reflected electrons and positrons impinging on a bent crystal has been measured by the H8RD22 Collaboration on the H8 beamline at the CERN SPS. A dedicated spectrometer has been developed to measure high-energy photon spectra (up to ~100 GeV) under volume reflection: photon and charged particle beams have been separated by a bending magnet and leptons were detected and tagged by microstrip silicon detectors and a Pb-scintillator sampling calorimeter. A comparison between the experimental and analytical data for the amorphous and volume-reflection cases is presented and the differences are discussed.

Abstract

The trend of volume reflection parameters (deflection angle and efficiency) in a bent (110) silicon crystal has been investigated as a function of the crystal curvature with 400 GeV/c protons on the H8 beam line at the CERN Super Proton Synchrotron. This Letter describes the analysis performed at six different curvatures showing that the optimal radius for volume reflection is approximately 10 times greater than the critical radius for channeling. A strong scattering of the beam by the planar potential is also observed for a bend radius close to the critical one.

Abstract

A high performance apparatus has been designed and built by the H8-RD22 collaboration for the study of channeling and volume reflection phenomena in the interaction of 400 GeV/c protons with bent silicon crystals, during the 2006 data taking in the external beamline H8 of the CERN SPS. High-quality silicon short crystals were bent by either anticlastic or quasimosaic effects. Alignment with the highly parallel (8 mu rad divergence) proton beam was guaranteed through a submicroradian goniometric system equipped with both rotational and translational stages. Particle tracking was possible by a series of silicon microstrip detectors with high-resolution and a parallel plate gas chamber, triggered by various scintillating detectors located along the beamline. Experimental observation of volume reflection with 400 GeV/c protons proved true with a deflection angle of (10.4 +/- 0.5) mu rad with respect to the unperturbed beam, with a silicon crystal whose (I 11) planes were parallel to the beam.

Abstract

The doubling of the angle of beam deflection due to volume reflection of protons by a sequence of two bent silicon crystals was experimentally observed at the 400 GeV proton beam of the CERN SPS. A similar sequence of short bent crystals can be used as an efficient primary collimator for the Large Hadron Collider. (c) 2007 Elsevier B.V All rights reserved.

Abstract

We investigated the effect of annealing on the crystalline quality of Ge epilayers grown on low porosity porous silicon (pSi) buffer layer and on bulk Si by LEPECVD. High-resolution XRD analysis indicates that during annealing, Ge grown on pSi undergoes a stronger reorganization compared to Ge grown on Si in terms of strain distribution and mosaic broadening. Strong morphological reorganization of the pSi buffer during annealing leads to a stronger reduction in Ge mosaicity as compared to annealed Ge on bulk Si. This improvement is attributed to bending of threading dislocations in a plane parallel to the growth interface, which is attributed to a strain field introduced by pSi within Ge during their simultaneous reorganization at high-temperature. After cyclic annealing at 750 °C, plan view transmission electron microscopy analysis revealed a threading dislocation density for Ge on pSi which is about one order of magnitude smaller than for annealed Ge on bulk Si. Ge on pSi virtual substrates thus represent a promising platform for the growth of III-V and GeSn semiconductors on Si with a low cost and high-throughput technique. [ABSTRACT FROM AUTHOR]
