description Hefei Advanced Light Facility (HALF) uses a grid-controlled thermionic cathode gun as its electron source of the linear accelerator. The nanosecond grid-controlled power supply is an important part of the electron gun power supply system, and its performance will affect the quality of the beam. To achieve the requirements of the electron gun for nanosecond pulse power supply, we use the series-parallel multi-stage avalanche transistor scheme to achieve nanosecond fast pulse output. The test results show that the power supply not only can meet the requirements of HALF for its electron gun but also have good waveform repeatability and amplitude stability.
