最近提出的感应同步加速器(IS)[1]中的关键装置是一种快速开关感应加速装置。IS概念的第一个应用是强度倍增器(ID)[2]，它被认为是对KEK-PS的重大升级。KEK、东京工业大学和日兴公司正在合作开发一种用于ID的感应加速装置和全固态功率调制器。调制器必须切换峰值电压为10KV，脉冲重复频率高达880千赫。加速需要1微秒的有效脉冲持续时间。同时，需要40-100毫微秒的较短的持续时间来产生势垒桶，从而实现长束，即所谓的超束。经过对各种磁芯材料的铁损测量和开关元件的选择，组装了感应模块和调制器的样机，并成功地工作在100 kHz，脉冲串为10个脉冲。除了设计研究和基本损耗测量的结果外，还给出了在开关性能方面观察到的初步结果。
The key device in the recently proposed Induction Synchrotron (IS)[1] is a rapidly switched induction acceleration device. The first application of IS concept is the Intensity Doubler (ID)[2] which is under consideration as a major upgrade of the KEK-PS. The collaboration between KEK, Tokyo Institute of Technology, and Nichicon is developing an induction acceleration device and an all solid-state power modulator for the ID. The modulator must switch peak voltage of 10kV with pulse repetition rates of up to 880 kHz. An effective pulse duration of 1µsec is required for acceleration. Meanwhile, a shorter time-duration of 40-100nsec is required to generate the barrier bucket, achieving a long bunch, socalled super-bunch. After careful core-loss measurements for various magnetic-core materials and choice of switching elements, a prototype of induction module and modulator has been assembled and successfully operated at 100kHz with a burst of 10 pulses. In addition to the results of design studies and basic loss measurements, preliminary results observed in the switching performance are presented.
