【Abstract】 A sort of triggering generator with fast rise time and amplitude of 100 kV is developed, its primary specifications are as following: nominal operating voltage amplitude of 100 kV, the rise time of the pulse voltage of 10 ns, the pulse width (FWHM) of 80 ns and the jitter less than 10 ns. The working principal of the generator is that the charging capacitor with low inductance discharges through the high-voltage output coaxial cables by a spark gap to produce a high voltage pulse. The triggering generator reaches the objectives of fast rise time and low jitter by adopting coaxial configuration and field-distortion SF 6 gas spark switch. It consists of four main parts: pulse forming chamber, electrical controlling system, gas controlling system and high voltage power supply. The design of every part, experimental results and analysis are presented in detail in this paper.更多还原
