Abstract :
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 over 8MHz input bandwidth and over 60dB dynamic range required by the spectrometer. With the intelligent design in its main FPGA, this 704 channels DAQ could be self-pre-triggered by each recoil event and transmit the data of over 1000 events per second through only one universal Ethernet interface.
