Abstract：Boron coated straw neutron detectors are being developed for use in the small-angle neutron scattering (SANS) instrument of the compact pulsed hadron source (CPHS) in Tsinghua University. This paper describes the readout electronics system for the position sensitive detector. The position resolution is estimated based on a noise analysis of the detector and the front end electronics. Then, the circuit parameters are optimized to improve the output signal characteristics. The position resolution of the detector and the readout electronics were evaluated using a charge injection test and a neutron beam test, with a position resolution of 2.7 mm in the charge injection test and 4.5 mm in the neutron beam test. The results that the detector and readout electronics meet the requirements for the neutron position measurement in the CPHS SANS instrument.
