Description

In April 2024, work began at Daresbury Laboratory on the high-power conditioning of CLARA’s (Compact Linear Accelerator for Research and Applications) radio-frequency (RF) structures using proprietary automated RF conditioning software, N0-ARC (No Operator Automated RF Conditioner) to attain operational powers and pulse lengths. The four types of structure conditioned were an S-band standing-wave photoinjector (PI), known as the High Repetition Rate Gun (HRRG); four S-band travelling-wave linacs (L01–4); an S-band standing-wave transverse deflecting cavity (TDC); and S-band waveguides under vacuum. Here we present the conditioning progress for each structure in terms of power, RF pulse length, number of pulses and total breakdown count. Key features are highlighted and discussed, along with fallback conditioning strategies.
