Abstract

From 2011, the Pohang Accelerator Laboratory (PAL) had started the 10 GeV PAL-XFEL project. The PAL-XFEL needs a highly stable electron beam. The very stable beam voltage of a klystron- modulator is essential to provide the stable acceleration field for an electron beam[1]. Thus, the modulator system for the XFEL requires less than 50 ppm PFN voltage stability. To get this high stability on the modulator system, the inverter type HVPS is a pivot component. The requested specification of the inverter power supply is being developed the 50 kV, 5 kJ/sec 1 sets and 30 kJ/sec 4 sets at the PAL. In this paper, we will discuss the development and the test results of the inverter power supply for pulse modulator system for obtaining machine stability.
XFEL高精度高压CCPS的研制
从2011年开始,浦项加速器实验室(PAL)启动了10 GeV PAL- xfel项目。PAL-XFEL需要高度稳定的电子束。速调管调制器非常稳定的束流电压对于电子束的稳定加速场至关重要[1]。因此,XFEL的调制器系统需要小于50 ppm的PFN电压稳定性。为了在调制器系统上获得这种高稳定性,逆变式HVPS是一个关键部件。在PAL,逆变电源的要求规格为50kv, 5kj /sec 1组和30kj /sec 4组。本文将讨论用于脉冲调制器系统的逆变电源的开发和测试结果,以获得机器稳定性。
