• 論文の詳細を見る

• A He^3 Cryostat, designed for a far infrared detector, is described. A detector temperature is lowered by reducing the vapor pressure of a He^3 bath with an activated charcoal pump atliquid He^4 temperature, which is fixed just above the liquid He^3 bath. Adsorption and desorp-tion of He^3 gas using the pump are controlled by changing the temperature of charcoal.A temperature of 0.33 K was obtained at the detector table under the condition of heat input of 30 μW. This temperature was maintained about 7 hours with 1000 cm^3 (STP) of He^3 gas.The time required for cooling the detector table from 1.7 K to 0.3 K was 3 minutes.
