A pulse compressor in form of a SLED cavity was added later to enable single klystron operation for redundancy in case of a modulator failure. The SLED was successfully commissioned in May 2017 including remote selection of single klystron with SLED operation without degradation of beam energy. Two years on there have been some unexpected operational benefits including reduced phase sensitivity and drift allowing repeatable injection based solely on diagnostic phase read backs. Temperature stabilised power amplifiers based on S band GaN radar technology are being trialed in the meantime with a goal to set and inject with minimal operator adjustment. The results from the SLED cavity upgrade are shown and the latest S band radar technology designs are outlined.
