Title: A Conduction-Cooled SRF Cavity: Apparatus and First Results

Abstract

First ever demonstration of accelerating gradients on a cryogen-free, cryocooler conduction-cooled SRF cavity • Niobium cavity produced >1.5 MV/m with a 2 W @ 4.2 K cryocooler • There is considerable scope for improving the thermal management in our setup • Ongoing: mitigation of static heat leak • An Nb3Sn coated cavity is projected to yield >10 MV/m accelerating gradients on our existing setup • Tests are planned for the near future
