High voltage fast ramp pulse generation using avalanche transistor

The authors have developed an avalanche transistor based pulser for use as a pockel cells driver and for gating a microchannel plate. The output voltage ranges from 1–4 kV to 50 Ω, with fall times of 200–300 ps. The repetition rate is less than 1 kHz. The trig jitter is less than 100 ps. Trig delay is about 8 ns.
