Building upon 50 years’ experience, we offer a wide range of wet superconducting magnet systems. The magnets can be integrated with our range of ultra-low temperature inserts including dilution refrigerators and ³He refrigerators.

Up to 22 T from standard
Wide range of temperatures from 1.5 to 300 K, depending on the variable temperature inserts
Can be integrated with our range of ultra-low temperature inserts including dilution refrigerators and ³He inserts
Ideal for high vibration sensitive experiments
Optimised, low loss, high temperature superconductor current leads as standard

Compensation coils can be used to improve the homogeneity at the centre of the field by reducing the rate at which the field drops at the end of the coils
Shim coils are used to remove residual field gradients, and may be wired in series with the main coils to give a basic level of correction ('series shims') or independently to give finer adjustment ('independent shims' with their own ISS10 shim power supply)
Modulation and gradient coils can be fitted into the bore of the magnet to provide a modulated (typically sinusoidal ac) magnetic field or a field gradient across the sample space. A single coils offers both options, and is powered via a separate set of current leads
Cancellation coils may be fitted above and/or below a magnet to give a low field region close to the centre of field, frequently used with dilution refrigerator systems

Further magnet options, vector rotate, split pairs and more are available, please see our Custom & Speciality page or alternatively c ontact us for details.

Solenoids are fitted in a cryostat (dewar) and various dewar options are available as below:

Low loss liquid-nitrogen shielded dewar
IntegraAC - helium recondensing dewars
Vapour sheilded dewar for minimum vibration
Lambda point refrigerators available for 2.2K magnet operation
All stainless steel dewar for high field systems

Further dewar options are available through custom designed magnet systems - please contact us for details.
