โœฆ Synopsis

A compact 3He cryostat with a charcoal adsorption pump was constructed for use in thermometry. The cryostat fits into a liquid helium storage tank with a 51 mm neck. The 3He gas is held in a cylinder on top of the cryostat. The sample volume of the cryostat is 30 mm in diameter and 70 mm in height. The base temperature is 0.34 K and the cooling power is 1.5 mW at 0.5 K, with a hold time of more than 10 h with 7 ml of liquid 3He and a turnaround time of ~30 min.
