โœฆ Synopsis


Both mechanical and fountain-effect pumps are being considered for use in the in-orbit resupply of superfluid helium to a number of scientific instrument systems. This Paper presents a review of the operating characteristics of these pumps. Particular emphasis will be given to the different methods of evaluating the efficiency of these pumps and their effectiveness in a transfer system.

The Space Infrared Telescope Facility(SIRTF) will be a large infrared observatory cooled to 2 K by 4000 dm 3 of superfluid helium, and expected to have a lifetime of ~2 years on orbit. Concepts are presented for replenishing the cryogen on orbit, and for designing the airborne support equipment requ
