Sub-ns Jitter, 1ns Risetime and 10 kV Rectangular Pulse Trigger Generator

A new rectangular pulse trigger generator has been developed which can generate two 10 kV pulses with a risetime less than 1 ns, a jitter of 0.2 ns and a width of about 10 ns and 40 ns, respectively. This generator uses two polymer-foil switches and 25 ohm Blumlein transmission lines composed of two-parallel standard coaxial cables discharging into two 50 ohm output cables. The pulse width and the delay between two pulses can be adjusted by changing the length of the cables.

基于薄膜开关的全自动快前沿高压方波发生器研制

本文研制了一台基于薄膜开关的全自动方波发生器，设计了紧凑化低电感薄膜开关，分析了影响薄膜开关输出特性的因素，包括回路电感、阻抗、传输线长度、杂散电容、电感等对输出波形的影响；设计了自动换膜结构及基于触摸屏和PI。C控制的全自动控制系统。实测了方波发生器的输出波形，输出电压幅值2～8kV可调，前沿1．25ns，脉宽20～100ns可调。该装置在高压脉冲分压器标定、电磁脉冲效应研究等领域有广泛的应用价值。
