Features

  • Low-loss Dewar with liquid nitrogen jacket and Brass LTS Leads optimised for persistent, low helium boil off operation.
  • Integrated lambda-point fridge allows cooling the magnet to 2.2 K to extend the magnetic field range.
  • Compatible with our variable temperature insert (VTI) for 1.5 K – 300 K operation
  • System is compatible with VTI, KelvinoxMX, KelvinoxTLM, KelvinoxJT and HelioxVL product line.

  • Compatible with our range of ³He refrigerators and dilution refrigerators to reach temperatures below 10 mK.

Options / Accessories

  • 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.
  • Vapour sheilded dewar for minimum vibration.

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

The MercuryiPS is an intelligent fully configurable magnet power supply system. It enables automated control of a wide range of superconducting magnets, including NMR, high field, beamline and Vector Rotate magnet systems. MercuryiPS is a bi-polar, high-stability, four quadrant power supply with incorporated quench protection. It includes temperature control of the main high-power sense resistor to prevent output current drift. The MercuryiPS is fully controllable by remote command via TCP/IP, USB, RS232 or optional GPIB.

The MercuryiTC is a versatile cryogenic environment controller. In its basic form it includes a single channel high-resolution (24 bit) temperature measurement circuit which supports all the standard cryogenic sensors (ruthenium oxide, cernox, silicon diodes, platinum, thermocouple and RhFe). With the constant voltage mode it enables reliable, accurate temperature measurement using negative temperature sensors (NTC) down to below 250 mK. The base unit enables PID loop configuration control of a single heater output up to 80 Watts (40 V, 2 A).
