5 ©2003 Qi3 Ltd Superconductivity UK The cryogenic challenge October : A respected physicist has been awarded a Nobel Prize for his continuing research into one of the most important breakthroughs in medical science. Sir Peter Mansfield the first Nottingham academic to receive such an accolade has been awarded the 2003 Nobel Prize in Medicine for his work in the application of magnetic resonance imaging (MRI) to medical diagnosis - a breakthrough now recognized to be comparable with the discovery of x-rays. The award has been bestowed upon Sir Peter jointly with US researcher Professor Paul Lauterbur, also an international leader in the field of MRI. Many thousands of superconducting MRI systems are installed around the world

26 ©2003 Qi3 Ltd Superconductivity UK Cryomech Cryomech, Inc. manufactures single and double- stage Gifford-McMahon and Pulse Tube cryorefrigerators. They have developed the AL300 and the AL330, and claim that they have the highest efficiency and cooling capacity to date of any available GM cryocooler at temperatures from 20 to 60K. Current research includes the development of a new generation of Stirling-type (valveless) pulse tube cryocoolers for 60 to 80K and higher efficiency Gifford-McMahon cryocoolers for 20 to 40K Source: SpaceDaily Image copyright and courtesy Cryomech, Inc.

27 ©2003 Qi3 Ltd Superconductivity UK Stirling Cryogenics Manufacture Stirling cycle coolers LPC 1-8 (1 stage): 500W – 65K (4 models) GPC 1-4 (2 stage): 20K, 80K (2 models) Research ongoing in Stirling type Pulse Tube Coolers Recent Siemens project Siemens is testing High Temperature Superconducting Transformers for trains. These transformers operate at a temperature of 65K. Based on the SPC-4 cryogenerator, Stirling developed a cooling system using subcooled pressurized liquid nitrogen as a coolant. By using subcooled liquid nitrogen, no evaporation occurs and thus an optimal cooling of the transformer is established. Image copyright and courtesy Stirling Cryogenics

31 ©2003 Qi3 Ltd Superconductivity UK There are still cooler choices Pulse tubes have their disadvantages: e.g. Cryomech GM-PTC 77K has 3.8kW input 77K has 2.2kW input They expect to achieve 85% of GM efficiency e.g. Stirling Cryogenics Early Stirling PTC has 50% of the efficiency of a regular Stirling cryocooler

32 ©2003 Qi3 Ltd Superconductivity UK Liquid cryogens Systems can still use: Liquid cryogens Liquid cryogens with recondensors Liquid cryogens with shield coolers Liquid cryogens with miniature liquefiers LN2, subcooled 63.5K Subcooled liquid 57K and other LOX/LN2 50.5K, all at 1 bar pressure And what about Neon and LOX?

34 ©2003 Qi3 Ltd Superconductivity UK Concluding thoughts Future industry consolidation Are we really taking cryogenics seriously? What about the use of liquid cryogens in conjunction with cryocoolers? And what about new designs of cryostat? Where are the Europeans? Is there an opportunity in the 20-50K region?
