In 2009 a vertical bath cryostat was commissioned at the S-DALINAC. Since then, components for the new cryostat module within the framework of the injector upgrade have been tested. Measurements have been performed to check the leakage rate of “Quick-CF” UHV flanges and the performance of piezo actors in superfluid helium have been investigated. To enlarge the scale of possible measurements at the vertical bath cryostat, systems to measure the quality factor via the decay time method and quench localisation via second sound will be implemented this year. We will report on the recent results.
