A numerical simulation of transient heat transfer for thermal insulating vacuum loss in the g-2 cryostats was verified by the cold test results on one cryostat ring. The temperature profiles of the superconducting coil mandrel and outer shell were obtained for helium, nitrogen, and air leaks. Temperature drop and thermal contraction of the cryostat shell due to vacuum loss excited some design concerns. Heating methods for the cold cryostat shell, such as blowing natural air to increase thermal convection, were also simulated.
