摘要
以"强光一号"加速器为例,给出了一种可以对其阴阳极间负载电压进行直接测量的自积分式电容分压器。介绍了自积分式电容分压器的结构,并通过静电场模拟分析了该分压器结构并不会对阴阳极间隙电场造成明显影响,在此基础上利用方波电压源对其进行了响应实验从而获得其频率响应,并对电容分压器的分压比进行了在线标定,最终给出了利用该自积分式电容分压器测量短路状态时阴阳极间隙电压测量结果。
A kind of self-integrating capacitive divider is introduced to measure the diode load voltage on the Qiangguang-Ⅰ accelerator. The structure of the divider is given first and the static electric field of the divider is simulated by ANSYS. The calculation result shows that no significant effect is induced on the electric field between the anode board and the cathode board, when the divider is located in a small hole on the anode board. By using the square pulse voltage generator and the standard resistance divider the frequency response and the attenuation ratio of the capacitive divider are calibrated. At last the divider-measured voltage of the short-circuit load on the Qiangguang- Ⅰ accelerator is given.
