Description
The LCLS Superconducting Linac’s continuous wave operation delivers a beam with 5–10 times higher energy stability compared to the LCLS Copper Linac. Transverse stability analysis identified low-frequency (up to a few Hz) injector laser motion on the RF Gun cathode. Furthermore, 60 Hz spectral lines from the spreader kicker were identified and corrected via kicker pulse timing adjustments. Intensity analysis revealed a low-frequency component likely coupled to transverse laser motion, alongside a 1690 Hz line suspected to be aliased down from a higher-frequency source. Data analysis, mitigation techniques, and future plans are presented.
