  • Abstract

    Based on THGEM thermal neutron position sensitive detector, a readout electronics system was designed with a specific integrated chip VA64TA2 to realize charge integration, amplification and conversion. Using high-speed analog-to-digital conversion chip AD9220 to realize data sampling, USB communication to realize data transmission, and FPGA as the main controller, the system was constructed. The array charge signal readout of the detector was realized. The channel input-output linear responses of the system are good, between ±15 fc. The centre-of-gravity read-out of position information was realized. The maximum counting rate of the detector could reach 1×105/s.
