Abstract

A particle track system was constructed in BEPC to trace the particle’s flight path. The multi-wire proportional chambers (MWPC) were used as detectors of particle flight path. The signal of MWPC was amplified by charge sensitive amplifier

converted to digital by charge integrating ADC. This article discusses the principle and linearity of charge sensitive amplifier. The result of simulation and the property of both charge integrating ADC and data acquisition system were described.
