| Abstract: | A picosecond high-voltage pulse electronic circuitry was designed using an avalanche transistor.The circuit contained an avalanche transistor circuit and a diode shunt shaper circuit.A high voltage fast-step pulse with a width of 6 ns and amplitude of 5 kV was generated by using avalanche transistors in a Marx bank configuration and was shaped by avalanche diodes.Finally,a short pulse wave form with a width of 230 ps and amplitude of 2.5 kV was achieved.The short pulse was used for driving photocathode,whic... |
