Abstract

Abstract

A resistive-voltage-dividing high-power load used for experiments of magnetically insulated transmission lines (MITLs) has been designed, and the resistance of this load can be changed from 2.0 to 14.0 . By using the system identification tool of MATLAB and the electromagnetism module of ANSYS, the frequency response and the surface electrical security of the load were studied, respectively. Also, the influences of the temperature and skin effect were particularly considered. The resistive load has been used for one-meter long MITL experiments on Qiangguang-Ⅰ accelerator. With the load resistance of 2.1 , the peak load voltage can reach about 1.2 MV, and the peak current can reach about 494.4 kA with a risetime of about 125 ns. The results of the measurement accord closely with those of the TLCODE calculations.
