A self contained cryogenic cooler, requiring only electricity to operate, maintains apparatus therein at cryogenic temperatures without introducing liquefied gas, and with a minimum of mechanical vibration. The cooler includes an elongated cylindrical insulated container with an end plate, the container having a vacuum conduction barrier and a heat shield radiative barrier so that the heat flow through the walls is small. The interior of the container and the apparatus are cooled by a mechanical cooler that achieves intermediately low temperatures, and a...
Apparatus for attaining cryogenic temperatures within its interior, comprising: an elongated container having insulated walls, one closed end, and an endplate covering the open end of the container; a mechanical precooler supported within the container by a first support joined to the endplate; a gas expansion nozzle supported within the container by a second support joined to the endplate; a gas supply line extending to the gas expansion nozzle from the endplate, the supply line including a first length of supply line contacting and precooled by the mec...
