 Superconducting magnet systems
Superconducting magnet systems
Fully integrated cryogen-free magnet systems. Choose from various options, from standalone to complete turnkey measurement systems. Helium-cooled systems are also available.


Standard superconducting magnet 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

With over four decades of experience and a worldwide installation base, we are a recognized leader in the design and manufacture of superconducting magnet systems. Our renowned SuperVariTemp insert operates from 1.5 K to 325 K, and is featured in the SuperVariMagOptiMag, and SuperOptiMag systems, and is also available as an independent insert for use with existing magnets. We also offer a variety of superconducting magnet systems that offer a room temperature bore (with inserts that reach 800 K) along with a variety of other systems that are designed for specific applications. These state-of-the-art systems feature integrated designs for the cryostat, magnet, temperature controller, and programmable power supply, together with a complete line of ancillary equipment. Our approach to superconducting magnet system design provides a variety of technical and cost benefits.

By maintaining flexibility over the specification and integration of the magnet, electronics, temperature controller, and cryostat, we are able to offer magnet systems with performance characteristics tailored to individual experimental and budgetary requirements.

Our staff of physicists and engineers has extensive experience in the design and operation of superconducting magnet systems and are uniquely qualified to assist you with every step of your system purchase, from experimental design to post-installation support. All systems are fully integrated and liquid helium tested at our Woburn, Massachusetts facility; installation, start-up, and training are available.
