Detector Readout Systems
mesytec MPRS-16 includes 16 channels of charge sensitive preamplifiers, shapers, timing filter amplifiers and leading edge discriminators. It provides two timing filter outputs, where each is the sum of 8 channels. It also provides a NIM trigger output which is the ored signal of the discriminators. It is well suited for high resolution timing and ADC gate generation. The input polarity and sensitivity can be selected in 8 steps by a rotary switch. The shaper outputs are designed to connect directly to standard peaksensing ADCs. The modules are especially well suited for single or double sided multistrip silicon detectors.
