本文研究了一种新型的同轴电容分压器。对电容分压器的电特性进行了理论分析，并对电容分压器的参数进行了计算和测量。其上升时间约为8ns，分频比大于2000。本实验室利用水脉冲形成线对强电子束加速器的脉冲高压进行了测量。该电容分压器可在纳秒内直接测量二极管电压，与积分器结合后，可在数微秒内测量PFL充电电压。与传统的电阻分压器相比，电容分压器具有紧凑、稳定、相对较高的分压器比、快速的响应时间以及对加速器的影响不大等优点。
In this paper, a new coaxial capacitive divider is investigated. The electrical characteristics of the capacitive divider are theoretically analyzed, and the parameters of the capacitive divider are calculated and measured. Its rise time is about 8 ns, and the divider ratio is over 2000. The divider is employed to measure the pulsed high voltages of an intense electron beam accelerator with a water pulse-forming line (PFL) in our laboratory. The capacitive divider can directly measure the diode voltage within nanoseconds, and when combined with an integrator, it can measure the PFL charging voltage with a duration of several microseconds. Compared with conventional resistance dividers, the capacitive divider has more advantages, such as compactness, stability, a relatively high divider ratio, a fast response time, and not much of an effect on the accelerator.
