Abstract：
There is high electromagnetic noise radiation in Hefei Light Source (HLS) klystron gallery, which is from pulse discharging of thyratron modulator. This paper expounds the components of discharging circuit of HLS modulator. On the basis of it, the paper analyses the generating of discharging noise of klystron modulator and puts forward the method about reducing discharging noise of klystron modulator.
