Abstract

A Blumlein topology based high peak power, high repetition rate, and low beam impedance fast extraction kicker system for ORNL Spallation Neutron Source (SNS) is being developed at Brookhaven National Laboratory. The large magnet window size, large deflecting angle, low beam impedance termination and fast deflecting field rise time demand a very strong pulsed power source to drive the SNS extraction fast kicker magnet. This system consists of fourteen high voltage modulators and fourteen lumped kicker magnet sections. All modulators will be located in a service building outside the beam tunnel, which is a revised design requirement adopted in the mid 2000. The high current pulses generated by the high power modulators will be delivered through high voltage pulsed transmission cables to each kicker magnet sections. The designed output capacity of this system is in multiple GVA. Its first article modulator has been constructed and is being tested. In this paper, we present the system overview, project status and the advantages of this new conceptual design.

用于SNS光束提取的大功率快速踢脚系统

布鲁克海文国家实验室正在开发一种基于Blumlein拓扑的高峰值功率、高重复率和低波束阻抗的ORNL散裂中子源(SNS)快速提取踢子系统。大磁窗尺寸、大偏转角、低波束阻抗终端和快速偏转场上升时间需要非常强的脉冲电源来驱动SNS提取快速踢动磁体。该系统由14个高压调制器和14个集总踢动磁铁组成。所有调制器将设于波束隧道外的服务大楼内，这是2000年年中采纳的修订设计规定。高功率调制器产生的大电流脉冲将通过高压脉冲传输电缆输送到各踢脚磁铁段。该系统的设计输出能力为多GVA。它的第一个文章调制器已经建成并正在测试中。在本文中，我们介绍了系统概述，项目现状和这种新的概念设计的优势。
