Superconducting magnet systems

Standard system features:

• Top sample loading and exchange at all temperatures
• Effortless sample rotation and translation about the vertical axis at all temperatures, with options for rotation about a horizontal axis
• Field-independent thermometry
• The SuperVariTemp system, with provision for a temperature control thermometer at the heat exchanger
• Vapor cooled/superconducting high current magnet leads
• Superconducting magnets with persistent mode operation providing field stabilities of 20 ppm/h
• Carefully designed magnet support inside the helium reservoir, with optical access through the Dewar vacuum space (OptiMag and SuperOptiMag systems)
• Built-in superconducting liquid helium level sensors, providing continuous or timed level monitoring
• Readily accessible and interchangeable sample chambers

Complete systems include:

• Programmable magnet power supply with computer interface and bi-polar operation
• Temperature controller with field independent thermometry
• Liquid helium transfer lines
• Cryogenic Hall probe and gaussmeter
• Automatic nitrogen filling mechanism
• Vacuum pumping stations
