Cryomagnetics offers a full line of high quality superconducting magnet systems that are cooled to 4.2K without the use of liquid cryogens, allowing one to eliminate the issues associated with handling liquid cryogens. This is very important in many areas of the world where liquid helium prices are exorbitant, or in environments where transferring liquid cryogens is difficult.
Due to the elimination of liquid cryogen reservoirs, liquid cryogen free systems are often a fraction of the size and weight of conventional, liquid-based systems. This allows placement of cryogen-free superconducting magnet systems in areas not suited for liquid-based systems. Finally, the simplicity of cryogen-free system operation is very attractive. Simply plug in the cryocooler and operate the system. Today's cryocoolers are very reliable with minimal routine maintenance.
Cryomagnetics offers cryogen-free systems based on two different cryocoolers - 4.2K Gifford-McMahon or 4.2K pulse tube.
4.2K GM
The 4.2K Gifford-McMahon based systems by Cryomagnetics offer the flexibility of up to 1.5
watts cooling power at 4.2K and the capability of orienting the cold head in any position.
A popular configuration involves mounting the magnet system on a stand that allows
rotation of the room temperature bore, allowing access in either vertical or horizontal
positions.
Compressors are available in either air or water cooled.
4.2K Gifford-McMahon cryocoolers are used extensively throughout the world and enjoy an excellent reliability record.
4.2K Pulse-Tube
Pulse-tube cryorefrigerators have no moving cold parts, so vibration due the cold head is
minimized. Eliminating the displacer in the cold head simplifies construction and
increases reliability.
Cryomagnetics manufactured the first commercially-available superconducting magnet system based on a 4.2K pulse tube in 1999. Since that time, 4.2K pulse tube systems have become increasingly popular.
At present, the 4.2K pulse tube cryocooler is available with 0.5 watts cooling power at 4.2K and a water-cooled compressor.
