摘要
研制了一种结构简单、拆装方便的自积分电容分压器,用于测量强流电子加速器二极管输出电压。介绍了电容分压器的结构,计算了其电容量,并通过仿真的方法分析了前端电阻及其杂散参数对测量波形的影响,结果表明:当前端电阻杂散电容较大时,测量波形出现过冲现象; 而前端电阻对地电容较大时,会影响测量波形的前沿。将电容分压器用于测量强流电子加速器二极管输出电压,并运用水电阻分压器对其进行了标定,所测得波形与电阻分压器基本一致,分压比为563 007,可以用于测量半高宽为100 ns的高压脉冲。
Abstract
A kind of simple-mechanism, easy-disassembly self-integrating capacitive divider used for measuring diode output voltage of intense electron beam accelerator (IEBA) is developed. The structure of the capacitive divider is described, and the capacitance value of the capacitive divider is calculated by theoretical analysis and electromagnetic simulation. The dependence of measurement voltage on electrical parameters such as stray capacitance, earth capacitance of front resistance is obtained by PSpice simulation. Measured waveforms appear overshoot phenomenon when stray capacitance of front resistance is larger, and the wavefront will be affected when earth capacitance of front resistance is larger. The diode output voltage waveforms of intense electron beam accelerator, are measured by capacitive divider and calibrated by water resistance divider, which is accordance with that measured by a resistive divider, the division ratio is about 563 007. The designed capacitive divider can be used to measure high-voltage pulse with 100 ns full width at half maximum.
