Research on Triode Based High Re−Frequency Ultrafast Electrical Pulse Generation Technology

The high−repeat frequency ultrafast electrical pulse generation technology is mainly based on switching devices combined with circuits to generate pulses repetition frequencies of several kilohertz and a rise−time nanoseconds or even picoseconds. This the basis for research studies one key technologies that has received wide attention from various countries. problems be solved are high re−frequency high−voltage ultra−broadband transport circuit stability applicability, which include conduction mechanism research, time improvement recovery reduction. By studying avalanche transistor transient characteristics reducing loss in carrier process, influence each parameter output determined, factors enhance performance identified. paper designs new high−repetition electric (UPG) using pure electronics components, consists combining model 2N2222 hybrid Marx structure at same add filtering, fast diodes cutoff other matching techniques make its more stable, can obtain higher frequency, faster narrower widths. It been tested signal 200 kHz, leading edge 800 ps, half−high width 5 ns, an amplitude 1.2 kV jitter less than 5% generated load 50 Ω output. applied fields diagnosis, information countermeasures nuclear electromagnetic radiation research.
