Abstract
The system performance of the He II refridgeration system used in the Ebasco team SMES proof of principle experiment is described. The syste m 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 specia l attention, including the heat exchanger design, thermal penetrations , pumping, and plumbing, are discussed. Operating characteristics invo lving cooldown, lambda transition, and thermal perturbations are descr ibed. (C) 1997 Elsevier Science Ltd.
