Beam test results of the irradiated Silicon Drift Detector for ALICE

The Silicon Drift Detectors will equip two of the six cylindrical layers of high precision position sensitive detectors in the ITS of the ALICE experiment at LHC. In this paper we report the beam test results of a SDD irradiated with 1 GeV electrons. The aim of this test was to verify the radiation tolerance of the device under an electron fluence equivalent to twice particle fluence expected during 10 years of ALICE operation.Comment: 6 pages,6 figures, to appear in the proceedings of International Workshop In high Multiplicity Environments (TIME'05), 3-7 October 2005, Zurich,Switzerlan

INVESTIGATION OF AVALANCHE PHOTODIODES RADIATION HARDNESS FOR BARYONIC MATTER STUDIES

Modern avalanche photodiodes (APDs) with high gain are good device candidates for light readout from detectors applied in relativistic heavy-ion collision experiments. The results of the investigations of the APDs properties from Zecotek, Ketek, and Hamamatsu manufacturers after irradiation using secondary neutrons from U120M cyclotron facility at NPI of ASCR in Ä ReÄ z are presented. The results of the investigations can be used for the design of the detectors for the experiments at NICA and FAIR.

Application of ALPIDE pixel detector for heavy-ion nuclear experiment and ion therapy

International audienceWe present computer simulation data for the dielectric constant of a system of uniform polarizable spheres randomly distributed in a homogeneous background. The deviations from the Clausius-Mossotti formula are found for seven values of the volume fraction. In addition, the spectral density which appears in the Bergman representation of the dielectric constant is determined. The spectrum obtained with a sufficient number of higher-order multipoles differs significantly from that found with just dipolar or dipole-quadrupolar interactions
