Mini-MRI Systems
Magnets for Magnetic Resonance Imaging (MRI) are required to generate a high homogeneity field over the imaging volume which remains stable in time.

Neutron Scattering and Beamline Systems
For optical, neutron and particle beam experiments, Cryogenic offers a range of split pair magnets. These allow strong magnetic fields to be produced in a small volume with maximum access to the working space. Split pair coils can be mounted to provide either a vertical field with horizontal access or a horizontal field offering horizontal or vertical access.

Thermal Transport
The thermal transport probe measures thermal conductivity and thermoelectric power (defined by the Seeback Coefficient). Electrical and thermal contacts are made to opposite ends of the sample allowing for customisation to suit the sample requirements of the user.

Fast Ramping Magnet Systems
Cryogenic Ltd has developed a new range of fast-sweeping cryogen-free superconducting magnets using high-performance Nb3Sn coils. These magnets provide an ideal platform for XMCD and other polarity switching applications. No liquid cryogens are required offering superb economy and ease of use in comparison with liquid helium alternatives.

AC Susceptibility
The AC Susceptometer option uses a small primary excitation coil to apply an AC field to a sample (typically 1mT at frequencies from 0.1 Hz 10000 Hz). A pair of secondary pick-up coils positioned close to the excitation coils are used to detect the sample response.

High Resolution Magnet Systems
EPR
EPR samples with S=1/2 electronic spins exhibiting a narrow signal at G=2 and require magnetic fields of only ca. 3.5 T. However, EPR spectra from S>1/2 spins are typically much broader and have spectral features that spread over magnetic field range of several Tesla.

SQUID Magnetometer
S700X
The S700X SQUID Magnetometer is the most sensitive instrument for DC and AC measurement of magnetic properties as a function of magnetic field and temperature. Numerous different experiments may be performed with this unique instrument.

product
Cryocoolers
Cryogenic uses various cryocoolers with cooling powers to suit different cryogen free magnet systems and applications. The Gifford-McMahon cycle cryocooler has the advantage of greater thermodynamic efficiency. The pulse-tube cryocooler is vibrationally quieter, has a longer service interval and cools faster from room temperature.

product
Resistivity and Hall Effect
The Resistivity System allows the user to make Resistivity and Hall Effect measurements in the range of to M. Samples are mounted on special platforms inside the VTI with contacts made to the sample according to the customer's requirements.

product
Vector Field and Multi-Axis Systems
Cryogenic vector magnet systems allow precise alignment of the magnetic field to an exact direction in a measurement sample. The system provides the capability of orienting the magnetic field to any vector direction. This is suitable for experiments where samples cannot be moved easily.
