Analog FEE for High Counting Rate Transition Radiation Detector — •Vasile Catanescu, Daniel Bartos, and Gheorghe Caragheorgheopol — National Institute for Physics and Nuclear Engineering, Bucharest, Romania

The first version of a front-end electronics (FEE) based on Application Specific Integrated Circuit (ASIC) for high counting rate transition radiation detectors developed at NIHAM-NIPNE for CBM experiment at FAIR will be presented. The new front-end electronics consists of eight analog channels for TRD signals processing. The ASIC is designed in CMOS 0.35 microns AMS technology. Each channel has two analog outputs, one fast output with a semi-Gaussian signal useful for fast sampling ADCs and a second output with a peak sens information. The mother board contains some level translators and buffers for interface with standard acquisition system. This front-end electronics could easily fit with other high counting rate experiments.
