A London company, founded in 1970, that builds superconducting magnet systems and cryogen-free measurement systems for physics research.
Cryogenic Limited builds the powerful magnets and ultra-cold measurement systems that physicists use to study materials. Its magnets are made of superconducting wire, which carries electricity with no resistance when kept extremely cold, and they can produce very strong fields. The company is best known for cryogen-free systems, which use mechanical coolers called Gifford-McMahon coolers instead of liquid helium, a costly gas that is hard to get. A 2007 Physics World report said its systems reached 300 millikelvin and fields up to 17 tesla, and a later trade-show listing described solenoids up to 20 tesla and a measurement system covering 1.6 to 1000 kelvin.
Physicist Jeremy Good founded the company in 1970 and was still its managing director when Physics World profiled it in 2007. The company began developing cryogen-free magnets in the mid-1990s. At the time of that report its first 17 tesla system had gone to Stockholm University, and it was about to ship systems to India and Denmark. A 2014 exhibitor entry described it as a supplier of superconducting magnets to scientists for about 20 years. We found no written mission statement, and have not invented one.
A commercial registry aggregator lists Cryogenic Limited, company number 02659543, at Unit 6, Acton Park Estate, The Vale, London W3 7QE, incorporated in 1991. This is a third-party summary of the public register and should be checked against Companies House. The company exhibits at international conferences, which suggests a global customer base in universities and research institutes, but the sources do not name UK customers.
The sources we found say nothing about team size, working culture or recent news, and the newest of them is from 2014, so we cannot say what the company is like to work for today. What can be said from its history is that it is a long-lived, founder-led specialist, with a managing director, a director of sales named Renny Hall in 2007, and a product range that has grown from magnets to full measurement systems with probes for resistivity, magnetism and heat capacity.
People in a business of this kind include magnet and cryogenic designers, electronics and software engineers, workshop technicians who wind, assemble and test the magnets, and sales and support staff who talk to research groups. Physics, electrical engineering and mechanical engineering are typical routes in. Quantum research needs strong magnets and cold environments, so this is a supplier to the field rather than a quantum company in its own right.
