Description

The Projectile Spectator Detector (PSD) is a sampling lead/scintillator forward hadron calorimeter with transverse and longitudinal segmentation, which will be used to measure collision centrality and orientation of the reaction plane in the nucleus-nucleus collisions at the Compressed Baryonic Matter (CBM) experiment at FAIR. The PSD consists out of 44 modules with 10 longitudinal sections in each. PSD’s readout chain consists out of radiation-hard Front-End Electronics (FEE), Readout Modules with 14-bit 125 Msps ADCs and a Service Module with bias and calibration apparatus.

This article covers design and features of the FEE and readout electronics, as well as the results of the readout chain tests done with cosmic radiation signals and during the heavy ion beam runs at mCBM.
