Silicon-CsI detector array for heavy-ion reactions

An array of 60 silicon-CsI(T1) detector telescopes has been developed along with associated electronics, The close packing of the telescopes required novel designs for the photodiodes and the silicon Delta E detectors. Newly developed electronics include preamplifers, shaping amplifiers, test pulse circuitry, and a module to monitor leakage currents in the silicon diodes. The array covers angles from 5 degrees to 18 degrees in the 4 pi Array at the National Superconducting Cyclotron Laboratory at Michigan State University. It measures protons to 150 MeV and has isotopic resolution for intermediate mass nuclei. (C) 2000 Published by Elsevier Science B.V. All rights reserved.
