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,which is MCP coated with gold. The measured exposure time of the camera was as short as 80 ps.
