Abstract

This paper introduces a new type of chopper, which is similar to a beam transformer first discussed by R. Wideroe (1928). It is based on the fact that the RFQ has a rather small energy window. A pulsed beam transformer that provides 10% energy modulation to the beam in front of an RFQ can effectively chop the beam. It has fast rise- and fall-time and a short physical length. A prototype, which consists of a cavity and a high voltage pulsed power supply, has been constructed and tested. Two types of magnetic materials were tried for making the core of the cavity-the Finemet and the ferrite Philips 4M2. While the former gave good performance, the latter failed the test. Results from the bench measurements and a plan for beam tests are briefly described.
作为斩波器的波束变压器的设计与试验
本文介绍了一种新型斩波器,它类似于R. Wideroe(1928)首先讨论的波束变压器。这是基于RFQ具有相当小的能量窗口这一事实。脉冲波束变压器在RFQ前为波束提供10%的能量调制,可以有效地截断波束。它有快速的上升和下降时间和短的物理长度。一个由空腔和高压脉冲电源组成的样机已经构建并进行了测试。两种磁性材料分别是Finemet和Philips 4M2。前者表现良好,而后者未能通过测试。简要介绍了台架试验的结果和梁试验的计划。
