IntegraAC - recondensing helium magnet system

The IntegraAC range of recondensing helium systems has been developed to significantly reduce the consumption of liquid helium by recondensing helium gas evaporated within the system, this minimises running costs and conserves this limited resource. It is also compatible with a wide range of superconducting magnets.

  • Zero helium consumption (depending on operating mode) 

  • Temperature range from 1.5 to 300 K using variable temperature insert (VTI)

  • Compatible with existing ultra-low temperature inserts

Our range of helium recondensing dewars combined with our range of wet superconducting magnets is an alternative to using cryogen free magnets (or dry magnets). Not only do they minimise running costs and maximise experimental time but they also enable the most demanding magnet designs.

  • Wide range of temperatures from 1.5 to 300 K, depending on the variable temperature insert
  • Significantly reduces helium consumption and frequency of refills
  • Compatible with all the standard range of dilution refrigerators, 3He inserts, VTI and superconducting magnets. This means you won't have to disrupt your experiments when you are upgrading your existing dewar
  • Optimised, low loss, high temperature superconductor current leads as standard
  • The cryostat can be kept cold continuously which minimises the costs associated with cooling a sample

Oxford Instruments has unrivalled experience in the design of high field helium recondensing magnet systems. Recent installations in China, Japan and Australia have further strengthened the market acquired by us, working closely with key institutes in Europe and the United States. Oxford Instruments has been selected to supply a new neutron scattering magnet to the China Advanced Research Reactor (CARR). We have also supplied a state-of the-art high field magnet recondensing dewars to Diamond Light Source.
