Abstract : The construction details of several cryostats are discussed. One of the cryostats is built to accommodate the solenoid as well as the test area within the helium-cooled cryostat. The other two have their test sections exposed to room temperature. The basic parts of all three cryostats are made of copper tubing and have an outer compartment filled with liquid nitrogen and an inner compartment filled with liquid helium. These compartments are made of stainless steel. An overall heat balance indicates that the total heat leakage into the system amounts to 560 joules/hour. A single-section solenoid placed in one of those cryostats can generate a field of 15 koe in a 52 mm gap with a critical current of 14-17 amps. It is contended that the above system is capable of yielding 50-60 koe magnetic fields. (Author)
