Description

The VSR DEMO SRF 1.5 GHz cavities require a large tuning range of 1 MHz to allow for the desired operation, including a cavity parking mode. The tuning system composed of blade tuner, stepper motor, release mecha-nism, and pre-loaded piezos installed into frames features mostly components already validated and used for other applications. However, the operational demands for the VSR application require adaptation of some of the com-ponents and testing to assess performance during aug-mented operation. Here the results of all component tests, most performed at cryogenic temperature, are presented.
