Quench Detection on a Superconducting Radio-Frequency Cavity

Abstract

We study quench detection in superconducting accelerator cavities cooled with He-II. A rigorous mathematical formula is derived to localize the quench position from dynamical data over a finite time interval at a second sound detector.

Extracting discontinuity using the probe and enclosure methods

“…• Recently the time domain enclosure method had an application to a problem on a superconducting radio-frequency cavity [163].…”
