This article discusses the determination of the optimal location of the heat exchanger using helium cooled support and multi-layer insulation with evanescent dewar. Analytical and computational calculations, including cooling schemes using multiple streams of helium and single streams of helium, were performed to determine the optimal location of the heat exchanger between the support and the multilayer insulation and the heat loss from the dewar. The article also proposes a simplified optimization method to reduce the number of simultaneous equations. The numerical solution is based on the case of multilayer insulation with stainless steel support and epoxy glass fiber support. The result of the solution is shown as a curve for ease of use by the designer.
