โœฆ Synopsis

A mathematical model of the cooling of a continuous-flow cryostat which takes into account real values of the specific and latent heat of the cryogenic fluid and of the specific heat of the cryostat material is presented. The amount of liquid in the cooling fluid and four parasitic heat flows, caused by radiation and heat conduction in the construct/on materials and in the rest gas in the vacuum insulation, are also taken into account. The influence of different model parameters on performance, particularly in the non-stationary regime, is demonstrated by means of numerical solutions of the modelling equation& A quantitative criterion which assesses the properties of the planned cryostat, is formulated. The theoretical conclusions are compared with measurements performed on a continuous flow helium cryostat.

The required lifetime for the Astro-E X-Ray Spectrometer (XRS) is 2 years, with a goal of 2.5 years. To meet this requirement, significant advances in state-of-the-art longlife cryogenic systems are required. The XRS system is a hybrid neon/helium system with a final stage of cooling provided by an

The task of cooling a superconducting power transmission line in which the "go" and "return" streams of supercritical helium are in thermal contact through the cable dielectric is examined both analytically and using an exact numerical solution to the flow equations with real helium properties. Temp
