  • Abstract
    Instability of the active RF cavity field control loop was observed during experiments with beam-driven (passive) superconducting cavities in CESR when the cavity external Q factor was raised to a value above 1×107. A computer model was developed to study this instability and find a way to cure it. The results of simulations are presented alongside the experimental results.
