Abstract
A cryogenic system has been operational in TJNAF’s Hall C for four years. The design of this system is presented and the operational and control philosophy is discussed. The system consists of conventional rigid transfer lines and a unique flexible transfer line. The features and heat load measurements of this flexible line are presented. Operational data are stored continously on computer disc. There are typical plots of this data presented to illustrate system stability. The cryosystem for Hall C is used to operate the superconducting magnets of the HMS spectrometer and a cryogenic target for H2, D2 and He.
