The upgrade project of the RICH-1 of the COMPASS experiment
Original language description
A major upgrade of the RICH-1 of the COMPASS Experiment at CERN has been designed and implemented in less than two years, during the SPS shut-down period. It is a twofold project: in the peripheral region the existing Multi Wires Proportional Chambers with CsI are unchanged but they have been equipped with a new faster read-out electronics, while the photon detectors of the central region have been replaced with a completely new fast photon-detection system. It is based on the use of Multi-Anode Photo-Multipliers (MAPMTs) coupled to individual fused silica lens telescopes and read out by a fast electronics based on the preamplifier-discriminator chip and the F1 TDC chip. For the 2009 SPS run an upgraded version of the MAD4 chip, the CMAD, has been designed in CMOS technology and implemented on the RICH-1. We present the photon-detection design and construction and its characterization and measured performances. The full-custom ASIC CMAD will be also shortly described together with its
