Description

UKRI-STFC Daresbury Laboratory operates a flexible vertical test facility (VTF) for testing superconducting radio-frequency (SRF) cavities. Thanks to a series of expansion and upgrade activities, including a new cavity test insert, improved magnetic hygiene, and increased cooldown rate (principally to facilitate residual magnetic flux expulsion), the facility is now capable of testing a single high-beta 650 MHz PIP-II cavity (with fast cooldown), up to three high-beta 704 MHz ESS cavities, or a single 1.3 GHz cavity (either bulk Nb or thin film) per test cycle. The team are able to switch between 650 MHz, 704 MHz, and 1.3 GHz cavity testing configurations with minimal downtime between test runs. This contribution details the expanded capabilities resulting from the various upgrades, different modes of operation, and operational practices that enable cryogenic cavity testing at Daresbury.
