Title: Operation of an SRF Cavity Tuner Submerged into Liquid Helium

Abstract

There are several projects is going at FNAL that required to tune bare (undressed) SRF cavities when they sub-merged into superfluid Helium. We have used LCLS II tuner [1] mounted on the special mechanical structure to tune single cell 1.3 GHz cavity. To precisely control the resonance of 1.3GHz SRF cavi-ties during testing at the FNAL’s Vertical Test Facility, we install for the first time a double lever tuner and operate it when submerged into the liquid He bath. Both active com-ponents of the tuner: electromechanical actuator (stepper motor) and piezo-actuators are operated inside superfluid helium. Accuracy in controlling the SRF cavity resonance frequency will be presented. Specifics of the tuner opera-tion when submerged into liquid He will be discussed.
