Abstract

The European X-ray free electron laser (XFEL) [1] com- prised more than 800 TESLA-type super-conducting accel- erator cavities which are driven by 25 high-power multi- beam klystrons. For reliable, reproducible and maintain- able operation of the linear accelerator (linac), the low- level radio frequency (LLRF) system will process more than 3000 RF channels. Furthermore, stable FEL opera- tion demands field stability better than 0.01 deg. in phase and 0.01% in amplitude. To cope with these challenges, the LLRF system is developed on a MTCA.4 [2] platform. In this paper, we give an update on the latest electronics developments, improvements of the feedback controller al- gorithm and measurement results at FLASH
