Our cryomagnetics group operates and maintains a gaseous helium recovery system with a helium liquefier at its core that is capable of delivering 20 litre/hour with an average annual production of 55,000 litres. Both regenerated and fresh liquid helium are supplied to the department and to other local laboratories and organisations.
In tandem, our high field magnet facility enables us to continue our strong track record in high-field, low-temperature experiments on new and novel materials. Our world-class superconducting magnets provide steady fields up to 21T, while our liquid helium cryogenic systems allow access to temperatures in the millikelvin range. In addition, the Nicholas Kurti Magnetic Field Laboratory makes use of pulsed magnet technology and achieves fields of up to 70T – the UK’s highest available fields. Experimental techniques possible in our magnet systems include magnetometry, electronic transport, electric polarisation and optical measurements.
