Abstract
The PIP-II linac will include thirty-six beta=0.61 and twenty-four beta=0.92 650 MHz 5 cell elliptical SRF cavities. Each cavity will be equipped with a tuning system consisting of a double lever slow tuner for coarse frequency tuning and a piezoelectric actuator for fine frequency tuning. The same tuner will be used for both the beta=0.61 and beta=0.92 cavities. Results of testing the cavity-tuner system for the beta=0.61 will be presented for the first time.
