A windowed gas cryostat has been developed for studying systems requiring a near-zero vertical temperature gradient. Vaporized ln2 is used as the refrigerant for temperatures from 95 deg k to near ambient. The vertical temperature gradient across a 15 cm beryllium- copper block was less than 0.05 Deg k.
