Abstract :
The ATLAS muon spectrometer will employ cathode strip chambers (CSC) to measure high momentum muons in the extreme forward regions. Preamplification of the charge on the strips is performed in the amplifier shaper module I. Amplifier shaper module II performs the analog buffering, digitization of the charge signals from individual cathode strips and multiplexes the data into two fibre optics links at 1 Gbps each. We present the design architecture of the complete front end electronics chain and its performance. We also report on the production and testing status of overall on detector electronics.
