Evaluation of a 0–60 kV oil-switched picosecond rise-time 5 nanosecond pulse generator

摘要

In this paper we present the first implementation of our 0–60 kV picosecond rise-time 1–10 nanosecond pulse generator. The pulse generator will be used in future work to generate a (sub)-nanosecond streamer plasma for air purification research. The first implementation of the pulse generator is a single line pulse generator with an oil spark-gap which generates 5 nanosecond pulses with a 200 picosecond rise-time and can operate at a repetition rate of 1 kHz into a 50 Ω load. In this paper we evaluate its performance and describe how we measure the very short pulses with an integrated and calibrated D-dot sensor. Furthermore, we present 3D EM simulations of the 5 nanosecond pulse generator.
