DICECold Probe

A compact cryogen-free ³He system for use in a UHV environment, sample in vacuum, uses a closed cycle cooler with vibration eliminated by a bellows system. A 1K stage allows full condensation of the ³He charge which extends the hold time at a base temperature of 300mK to 40 hours, and gives a fast regeneration time

The 3ICEDIPPER insert with a large diameter will be designed specifically to operate within the clear neck of a custom made vapour shielded helium dewar. The dipper will have a large sample space with room to mount various components to for experimental work. The height of the system will also be minimised where possible to ensure it will integrate into the purposed laboratory. The insert comes with a self-contained 3He gas charge and includes our patented condensation process.

The system can be combined with one of our anti-vibration frames to reduce the vibration at sample.
