Abstract

Magnetically insulated induction voltage adders are pulsed-power accelerators widely used in various fields. Preliminary cavity experiments concerning the current uniformity have been done on a prototype induction cavity. The cavity is single-point fed by a 1.0-MV/200-kA/60-ns pulse of Chenguang accelerator. Three different configurations of azimuthal lines are tested. The results indicate that the azimuthal variations of feed currents for all these configurations are less than 40%. And under this extent of nonuniformity, the current distributions slightly affect the cavity output voltage. An electromagnetic (EM) model is proposed for this prototype cavity. The characteristics of cavity output responses and current uniformity are simulated and analyzed. The EM model could reproduce the major experimental results well.
