MSGCROC - an ASIC for high count rate readout of position sensitive Microstrip Gas Chambers for thermal neutrons

In this paper we report on the development of an ASIC for readout of position sensitive neutron detectors based on low-pressure Micro-Strip Gas Chambers with solid composite

cps for a detector area of 25×25 cm
²
covered with 400×400 strips requiring 2 ns time resolution for coincidences of signals from X- and Y-strips set very demanding requirements for the ASIC performance.
