The invention discloses a digitized signal processing system for a tokamak anti-Compton gamma energy dispersive spectrometer. Analog signals generated by a primary detector and a secondary detector enter into a signal processor to be respectively amplified, shaped and timed, and then enter into a high-speed digitizer; the analog signals are converted into digital signals; then the digital signalsenter into an FPGA (Field Programmable Gate Array) for signal coincidence and anticoincidence processing to obtain anti-Compton data; then electrical signals are converted into optical signals througha photoelectric conversion bridge; the optical signals enter into a computer through an optical fiber and a computer data docking card in turn to obtain anti-Compton gamma energy spectrum data; and finally the data are uploaded to a database. By adopting the digitized signal processing system for the tokamak anti-Compton gamma energy dispersive spectrometer disclosed by the invention, the high-speed digitization and the coincidence and anticoincidence real-time processing of the signals of the tokamak anti-Compton gamma energy dispersive spectrometer are effectively implemented, the complicated traditional analog signal electronics system is greatly simplified, and the digitized signal processing system is very suitable for data acquisition and processing of the tokamak anti-Compton gammaenergy dispersive spectrometer.
