Abstract content

The stable and reproducible generation of a high average brilliance photon beam at Free Electron Lasers requires a high-precision radio frequency regulation of the accelerating fields inside the cavities. ELBE (Electron Linac for beams with high Brilliance and low Emittance) is a multi-purpose radiation source at HZDR (Helmholtz-Zentrum Dresden-Rossendorf). The LLRF system controls two normal conducting buncher cavities (one operating at 260 MHz and one at 1300 GHz), a super-conducting gun cavity and 4 super conducting TESLA-type accelerating cavities. Field detection resolution was improved and measurement results are presented. The system’s architecture and possible future system developments are discussed.
