Repetitive trigger generator with low jitter and fast rise time

A repetitive trigger generator with low jitter and fast rise time is introduced and the principles of designing and choosing the units in the trigger generator are given. The trigger generator is composed with control unit, charging unit and pulse forming unit. The pulse forming unit is a capacitor-fast-discharging trigger with hydrogen thyratron. The repetitive rate of trigger can reach 100 pps (pulses per second), the delay time is about 225 ns, the jitter is about 1 ns, the rise time is about 26 ns and the FWHM (full-width at half-magnitude) is about 70 ns. The amplitude of electrical pulse on the load with high impedance is about -40 kV at 100 pps, -51 kV at 50 pps, -60 kV at single shot, respectively. The micro-closing of hydrogen thyratron is discussed. As the anode voltage increases
