Spectromag PT Cryogen free magneto-optical superconducting magnet system 1.5 K, 7 T

Our cryogen free magneto-optical superconducting magnet system, SpectromagPT is a split pair, horizontal field magnet system that provides optical access to a sample in a variable magnetic field and low temperature environment.

Key features and benefits:
• Magnetic fields up to 7 T in a compact geometry.  10 T option available on request.  Using the highest specification superconducting wire available on the market, supplied by our sister company Oxford Superconducting Technology
• Low temperature insert providing sample temperatures from 1.5 K to 300 K
• Ultra low temperature HelioxVT insert providing sample temperatures down to 300 mK
• Ultra low temperature KelvinoxJT insert providing sample temperatures down to 30 mK
• No gas flow over sensitive samples; the system uses a static exchange gas around the sample, preventing flow induced movement of delicate samples or measurements probes
• Quick sample change via top-loading probe.  The sample can be changed while the system is cold.  No need for complicated load-lock mechanism and reloading into the gas
• No contamination or blockages: using a sealed circulation loop to the sample exchange gas.  This also increases the continuous running period of this system
• Enables full sample rotation for measurements both parallel and perpendicular to the field.  Via 30 mm clear diameter sample tube
• Sample rod with optional ±15 mm axial adjustments and 360orotation around a vertical axis
• Excellent optical access in the horizontal plane both parallel and perpendicular to the field

Control system
All standard electronic items are provided with LabVIEW® drivers to allow control through the Oxford Instruments LabVIEW System Control Software.  The software allows users to control the sample temperature and magnetic field.  In addition it is possible to integrate with other virtual instruments to provide full experimental control.
