Abstract

Fast cool-down is usually implemented with J-T cryocoolers which also enable low-cost and small-scale systems. In this paper, we describe an analysis for achieving cool-down time of a few seconds to 88K, using argon as the main coolant, and a few minutes of steady state cooling. It appears that in certain conditions a simple fixed orifice cryocooler may reach the performances of cryocoolers with a pre-cooling stage. Therefore, according to system demands, cost reduction, reliability, and manufacturing considerations the use of argon as a single coolant may be preferable over pre-cooling with another coolant, such as krypton. The investigation was made by a detailed numeric simulation and the results were successfully verified against experimental data.
