✦ Synopsis

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 experimental evolution of screen temperatures and the evaporation rate in steady conditions has been compared with computer calculations. Results obtained from each configuration and the options chosen for a 1 MJ SMES cryostat are presented.

Processing accuracy is an important area studied in rapid prototyping (RP) research. It is mainly dependent on the processing parameters, material characteristics and many other factors. Studies on processing accuracy can be divided into two categories: in-plane processing accuracy and vertical proc
