Computer-aided design of nitrogen-free helium cryostats

Novel computer-aided technique for optimization of the cryogenic storage sy stem performances is proposed. A new method of optimization, i.e., rotating coordinates (MRCs) with random search is applied and the parameters of cry ogenic storage vessels are computed. The optimum geometric sizes of the sys tem and a set of possible materials for its manufacturing are defined on th e basis of the computation results. The developed software for computer des ign of cryogenic system is created on Microsoft C for MS DOS. The results o f computation are analyzed in comparison with experimental data.
