| Title | Upgraded multiprobe sample inserts for thin film SRF cavity developments |

| Abstract | Optimisation of thin film (TF) coating parameters for producing SRF cavities requires rapid testing of superconducting properties. A dedicated multiprobe facility built at Daresbury Lab, based on a liquid He free cryocooler, allows such measurements to be performed. The facility has vacuum tubular inserts where the sample probe is loaded and cooled with He gas. The experimental inserts were either newly built or upgraded: (1) A DC resistance experiment allows measurements of critical temperature (Tc) and residual resistance ratio (RRR) on non-conductive substrates (e.g. sapphire). A newly designed insert allows better temperature control and easier sample change. (2) A new insert for magnetic field measurements of Tc on both conductive and non-conductive substrates. (3) An existing insert for planar magnetic field penetration experiments was significantly redesigned. It operates at lower temperatures (> 5.5 K), parallel magnetic fields < 600 mT, increased sensitivity, and enables measurements of field of first flux penetration (Bfp) and Tc on various substrates: copper and sapphire, the latter of which was impossible to measure with an older design. |
