Description
The PAL-XFEL LLRF and SSA systems have contributed to the stable operation of PAL-XFEL for nearly a decade with their reliability and robustness. Key achievements of these systems include the development of pulse-by-pulse real-time RF switching function for simultaneous operation of the HX and SX beamlines, development of a converter-type X-band LLRF, and development of a function to improve RF amplitude drift. The systems have faced various challenges during their operation, such as the arrival of key component life cycles, the discontinuation of key components, and the need for upgrades to keep pace with technological advances. Therefore, the following activities are being pursued. The PAL-XFEL LLRF and SSA systems have been field-proven, so upgrades are being carried out based on the existing systems. The discontinued processing PCs have been upgraded to higher-performance industrial boards, the RF modules are being redeveloped, and the A/D and FPGA boards are planned to be upgraded with new FPGAs and PCIe. In addition, an updated SSA prototype has been developed.
