Readout electronics of silicon detectors used in space cosmic-ray charges measurement
A readout electronics used in space cosmic-ray charges measurement for multi-channel silicon detector and its performance test results are introduced in this paper. A 64-channel charge sensitive ASIC (VA140) from IDEAS company is adopt in this method. With its features of low power consumption, low noise, large dynamic range and high integration, it can be used in future particle detecting experiments base on silicon detector.
