Cooling flat plate powder samples to 12 K

The PheniX is a unique closed cycle helium cryostat specifically designed for powder diffraction at very low temperatures. The PheniX is designed to be mounted onto a vertical goniometer and can be supplied with mounting plates for various powder systems.

The design of the PheniX means it is very easy to set-up and facilitates accessibility to the sample stage. For further information on integration of the PheniX with your powder diffractometer, we recommend you speak to the relevant manufacturer or contact us for further details.

  • Base temperature of 12K without liquid cryogens.
  • Fast cool down time, 20 K in 45 minutes, 12 K in 60 minutes.
  • Warm up time of only 40 minutes for fast sample change
  • High stability of 0.1 K
  • Complete programmability and ability to monitor and control remotely via Cryoconnector software and Oxford Connect
Mode of operation

A two stage Gifford McMahon (GM) closed cycle cooler made by Oxford Cryosystems is mounted within the body of the PheniX and operates using compressed helium gas provided by the Cryodrive compressor. Note that there is no helium gas consumption in this system and the helium gas circuit in the Cryodrive/Coldhead combination is sealed. The sample is cooled by the conduction of heat between the sample stage and the cold stages of the Coldhead, and the PheniX sample temperature is measured at the sample stage. Heat leaks within the PheniX are reduced by a radiation shield incorporating 0.005mm mylar windows, and the robust PheniX lid incorporates X-ray transparent windows of 0.25mm carbon fibre.

A number of 20mm diameter chromium plated copper sample stages are provided with the PheniX system, however different materials may be available at an additional charge. A vacuum system (supplied) is used to continuously pump the vacuum space around the PheniX internals and the rotating seal to minimise unwanted heat leaks into the system.
