Abstract
Many space instruments will require very low cryogenic temperatures to perform satisfactorily. The performance of bolometers greatly increases at very low temperatures and instruments for telescopes such as SIRTF will require a cooler to provide -50 μW total cooling power at temperatures of 0.1 to 0.3 K. With advances in cryogenic technology and satellite lifetime, the cryogen system design lifetimes are becoming much longer. This paper discusses a long life open-cycle 3He cooler that provides low cooling (50 μW) to a temperature as low as 0.18 K by continuous evaporation of liquid 3He and loss of vapor through a vent tube.
