摘要：
A compact He-3 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 He-3 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 He-3 and a turnaround time of almost-equal-to 30 min.
