Abstract

This paper presents the development and testing of a high-power 648 MHz/1.2 MW klystron power source for the superconducting elliptical cavities of the CSNS-II linac. With the CSNS-II upgrade, the linac beam energy is increased to 300 MeV, requiring efficient RF power sources. The newly developed 648 MHz klystron operates with a saturation peak power of 1.2 MW, a duty cycle of 6 %, and an efficiency of 50 %. The associated long-pulse solid-state modulator, capable of delivering high-voltage pulses with rapid response times, has been designed to drive four klystrons simultaneously. Experimental validation, including cold and hot tests of the klystron, confirms that the klystron meets the design specifications. These results provide a reliable foundation for the high-power RF system of CSNS-II.

CSNS-II直线加速器超导椭圆腔648 MHz/1.2 MW大功率射频系统

本文介绍了用于cns - ii直线加速器超导椭圆腔的大功率648 MHz/1.2 MW速调管电源的研制和测试。随着CSNS-II升级，直线光束能量增加到300 MeV，需要高效的射频电源。新开发的648 MHz速调管工作时的饱和峰值功率为1.2 MW，占空比为6%，效率为50%。相关的长脉冲固态调制器，能够提供具有快速响应时间的高压脉冲，已被设计为同时驱动四个速调管。实验验证，包括速调管的冷、热测试，确认该速调管符合设计规范。这些结果为CSNS-II的大功率射频系统提供了可靠的基础。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
