Cryogenic packaging for uniform cooling

摘要

A cryogenic package provides a cryogenic environment for devices that require temperatures of 150 K or below, with uniform cooling and minimal thermal stress. A cryocooler produces cold gas on a closed loop, and the gas is distributed in the chamber of a cryogenic vessel. The device housed in the chamber is bathed in a continuous flow of the gas. The warmed gas is returned to the cryogenic cooler.
