Pulsed fast discharge power supply of S2 laser

This paper selects the Blumlein circuit as the main discharge circuit and sets up the discretization equivalent model for the Blumlein circuit. The simulation and the optimum design of the circuit are carried out by using this model. A group of circuit component parameters are selected as the basis of mounting and adjusting the discharge circuit. The transmission line capacitor and stored capacitor are designed to reduce the parasitic parameters of the circuit and enhance the performance of the circuit. Experiment results indicate that the output voltage rising edge of the discharge power supply reaches the goal(5.08 ns) of the design, and that the discharge power supply works stably and plays an important role in S2 laser device.
