Investigations on Improvements of Oscillating Superleak Transducers

Three years ago, Oscillating Superleak Transducers (OSTs) were introduced by Cornell University for quench localisation on superconducting cavities, and are now used in several labs all over the world. There are several efforts ongoing to improve the design and accuracy of these devices. Additionally there are studies on improving the sensitivity of the OSTs themselves. This report presents the idea of changing the roughness of the electrode’s surface below the membrane.
