The Cryo-Pulse 5 Plus unit is an electrically powered cryostat for use with HPGe radiation detectors. It utilizes a pulse tube cooler, a highly reliable technology originally used in military and space applications and which has proven its value for germanium detectors in the original Cryo-Pulse 5 cryostat.

Like its predecessor, the Cryo-Pulse 5 Plus unit still consists of a cold head assembly, to which the detector is attached, and an external power controller. The basic external design and interface of the coldhead were preserved to maximize interchangeability between the previous and the current version. However the coldhead internals and the controller were completely redesigned and new features added to further improve the performance and reliability and to answer our customers’ requirements even better.

A pulse-tube cooler contains CFC free, non-flammable gas and is hermetically sealed, so no gas-refill is required. The compressor contains no oil or lubricant, so no contamination of the refrigerant occurs and no periodic filter exchange is required. This makes the Cryo-Pulse 5 Plus cryostat completely maintenance free.
