Experimental analysis of thermalisation and emissivity of radiation screens for cryostat design.

Author(s) : PEÓN G., CAMÓN A., MARTÍNEZ E., et al.

Type of article: Article

Summary

The article describes a method of characterising thermalisation and reflectivity of radiation screens in vertical vapour shielded cryostats after analysing the evaporation rate and key temperatures in steady state and some transient states. Variants on the thermalisation of the radiation screen to the helium container neck have been tested and effective hemispherical emissivities deduced for three different configurations of vapour shielded vertical cryostats. The options chosen for a 1 MJ SMES cryostat are presented.
