Compact CSC acquisition system: VXI D-size modules with a DSP interface

A complete electronics system has been developed, from the preamplifiers up to the readout and control interface, for the cathode strip chambers of the BBS spectrometer. The system is based on application specific D-size VXI modules. The size of electronics has been reduced by the use of small surface mounted daughter boards. A flat topped-pulse is produced with a new time-variant filter. In all modules, the 16-bit ADCs and FIFO memory are followed by a digital signal processor, which performs data filtering and cathode induced charge interpolation. Good analog noise performance is obtained in a multi-processor environment.
