A new fast neutron spectrometer based on recoil proton has been designed. The recoil angle and the energy of the recoil proton will be acquired by a 704 channels GEM-TPC. To read out the signals from each of the 704 pads of that TPC, an intelligent front end real time DAQ system has been designed. With the 40Ms/s sampling rate and the 12 bits resolution of each channel, this DAQ could operate with...
The subnanosecond time resolution readout system includes a time discriminator module and a TDC module is designed for reading the signals detected by the MCP from the X-ray pulsar. The periodicity of the signals from the specific pulsar will be detected under a high background level with this system. Through the delay chain designed in the FPGA, the time accuracy of this TDC module is able to reach...
