Abstract
An apparatus is disclosed for a flexible, easily reconfigured vacuum chamber capable of physical property measurement at cryogenic temperatures. The chamber is easily constructed from existing cryogenic pumps. The cryostat cold finger forms a cryogenically-cooled stage, upon which a wide variety of experiment test setups can be placed for measuring many different properties at cryogenic temperatures. The lid and feedthrough ports are reconfigurable to obtain measurements and interact with samples inside the vacuum. Attached heating elements enable testing at many possible cryogenic temperatures. The specific case of laser cooling at cryogenic temperatures is presented as an example, along with necessary lid and interior components. Viewports allow a laser beam into the chamber, while mirrors redirect this into the sample. Temperature diodes and laser power meters measure any heating or cooling effects.
