The Ponderomotive Effects of Narrow-band, Superconducting Resonators in Open and Closed Loop
Jacob Brown, Alexander Sukhanov, Crispin Contreras-Martinez +7
In this work, we present measurements of ponderomotive instabilities in narrow-band, coaxial resonators in open and closed control loop systems. We show an analytical scheme we wil…

Cold Test Results of Pre-Production PIP-II SSR2 Cavities with High-Power Couplers in the Fermilab Spoke Test Cryostat
A. Sukhanov, C. Contreras-Martinez, C. Grimm +13
As part of the PIP-II project at Fermilab, a pre-production cryomodule featuring 325 MHz Single Spoke Resonator type 2 (SSR2) superconducting RF cavities is under construction. The…
