The digital signal processing circuit based on FPGA has been designed in our development. The energy spectrum shift of the LaBr3detector at different ambient temperature has been studied and a temperature compensation algorithm has been designed. The test shows that the developed digital multi-channel spectrometer has good energy resolution and energy linearity, and the temperature peak-shift correction method is effective for LaBr3detector.
