Thermal Link Design for Conduction Cooling of SRF Cavities Using Cryocoolers
Ram Dhuley,Roman Kostin,Oleg Prokofiev,Michael Geelhoed,Thomas H. Nicol,Sam Posen,Jayakar Thangaraj,T. Kroc,Robert Kephart +8 more
TL;DR: In this paper, the authors present a thermal analysis of a conduction-cooled superconducting radio frequency (SRF) cavity that identifies the link thermal conductance requirement, using published or expected RF dissipation characteristics of an Nb3Sn coated niobium cavity and measured cooling capacity of a pulse tube cryocooler.
