摘要

高梯度加速腔是开发紧凑型直线加速器的主要研究方向之一。然而，这种加速腔的运行目前受到非线性电磁效应的限制，这些效应在高电场下会加剧，如射频击穿、暗电流和辐射。欧洲核子研究中心（CERN）设计并建造了一个用于医疗应用的新型常导高梯度 S 波段后向游波加速腔（v = 0.38c），其设计梯度为 50 MV/m。本文介绍了在 IFIC 高功率实验室对这种新型设计进行的高功率性能研究，以及结合数值模拟对调节参数进行的分析。

High-power performance studies of an S-band high-gradient accelerating cavity for medical applications

High-Gradient accelerating cavities are one of the main research lines in the development of compact linear accelerators. However, the operation of such accelerating cavities is currently limited by non-linear electromagnetic effects that are intensified at high electric fields, such as RF breakdowns, dark currents and radiation. A novel normal-conducting High Gradient S-band Backward Travelling Wave accelerating cavity for medical application (v = 0.38c) has been designed and constructed at CERN with a design gradient of 50 MV/m. In this paper, the high-power performance studies of this novel design carried out at the IFIC high-power laboratory are presented, as well as the analysis of the conditioning parameters in combination with numerical simulations.
