โœฆ Synopsis

The system performance of the He II refridgeration system used in the Ebasco team SMES proof of principle experiment is described. The system ultimately achieved a temperature of 1.85 K at a heat load of 37 W, and ran for 30 h without any problem. System elements requiring special attention, including the heat exchanger design, thermal penetrations, pumping, and plumbing, are discussed. Operating characteristics involving cooldown, lambda transition, and thermal perturbations are described.
