Description

In order to deal with the international problem of shortage of 3He, a new type of boron-coated Multi-wire proportional chamber (MWPC) thermal neutron detector is developed. Readout electronics for it, which can achieve good position resolution, is introduced in this paper. In this readout electronics, hit signal from MWPC detector is fed into the delay line module propagates towards to both directions. After be conditioned by front-end electronics (FEE), hit signal is signaled with differential Low Voltage Differential Signal (LVDS) level and fed to a Nuclear Instrument Module (NIM) time digitizing module. For the purpose of precision, simplicity and flexibility, the time digitizer s implemented in Field Programming Gate Array (FPGA). Each digitizer module can support up to 20 electrical channels. To correctly select the analog signal conditioning parameters, a complete theoretical analysis of the delay line module is put forward in this paper. Lab test shows that the time resolution contributed by readout electronics is better than 700ps with dead time about 550ns. Joint test with MWPC detector shows that the integral position resolution is better than 3mm which can meet the requirement of thermal neutron detection.
