Vb. Zalessky et al., PBWO4 SCINTILLATORS WITH NEW AVALANCHE PHOTODIODE READOUT FOR HIGH-ENERGY PHYSICS, IEEE transactions on nuclear science, 43(3), 1996, pp. 1307-1309
The main parameters of large-area avalanche photodiodes (APDs) with a
new structure of Metal-Resistive-Semiconductor layers (MRS) are descri
bed The first experimental data taken with a small PbWO4 (PWO) electro
magnetic calorimeter equipped with a new APD readout system in a 20-70
GeV electron beam at CERN are also presented.
