The convergence of high-quality Nb3Sn film coatings and cryocoolers with more than 1 W of cooling power at 4 K, makes it possible to envision superconducting radiofrequency cavities operating at accelerating gradients of the order of 10 MV/m, cooled by conduction with a crycooler rather than by contact with a liquid He bath. Such possibility might open the possibility of applying the SRF technology to industrial accelerators. This contribution describes the design of a test stand for conduction cooling experiments and the rf test results of a 1.5 GHz single-cell cavity cooled using a single cryocooler.
