A Method for In-Situ and In-Operando Cavity Loaded Q-Extraction in SRF Accelerators<br /><br />Abstract:<br /><br />A new method has been developed that allows extracting the loaded quality factor of SRF<br />cavities at any time during beam operation from acquired control system process parameters<br />without the need of additional measurement equipment. Concurrently it assesses the<br />attenuation in a cavities’ power transmission line for any RF generator to RF cavity<br />mismatch condition, hence<br />any beam loading condition, and thus can correct calibration inaccuracies of measured<br />forward and reflected power levels. <br />The described method has been applied first for all SRF cavities in operation at CEBAF<br />using archived process variables. <br />The beneficial use of the method as a diagnostic tool is demonstrated for a finite number<br />of cavities with surprising revelations. Recommendations are provided that could help<br />improving CEBAF operation and its power efficiency.<br />
