Description
The 3rd-generation synchrotron light source BESSY II is undergoing a series of modernization measures to maintain its leadership role until BESSY III starts its operation, planned for in 2035. The modernization of the LLRF control systems is one of these measures in the so-called BESSY-II+ project. Prior to the deployment of the new mTCA-based digital systems to control the fundamental frequency cavities at the booster and storage ring, a test stand was set up provide the opportunity for extensive offline testing and debugging. The test stand is consists of a HOM-damped 500-MHz cavity, a 80-kW Solid State Amplifier (SSA), a mTCA crate and all the ancillary systems required for high-power RF cavity operation. In this paper we discuss the results of the high power tests in continuous-wave operation, as required for the BESSY II storage ring, and in ramped mode, as required for the BESSY II booster during beam injection.
