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 Janis 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
