Cryogen Free Superconducting Magnet Systems


Janis Research Company is pleased to offer cryogen free superconducting magnet systems for both optical and non-optical applications. These systems are offered in both room temperature bore configurations and variable temperature integrated configurations for operation from below 2 k to 300 K. Non optical systems are also offered with vertical room temperature bore tubes, along with a top loading cryogen free cryostat for operation between 1.5 K and 300 K or higher. The magnets are typically cooled through reliable Gifford McMahon or pulse tube coolers for lower vibrations. The independent variable temperature cryostats can also be used separately for ultimate convenience.

Standard Configuration

Our cryogen free magnet systems can also be combined with microscopy cryostats, He-3 cryostats and dilution refrigerators to cover temperatures down to the 10 mK range or with high temperature inserts for operation up to 800 K. They are available to investigate a large variety of research studies such as Quantum Hall Effect, Quantum Dots, Mossbauer Spectroscopy, Magneto-Optical experiments, plus many others. They are also available with 2-Axis or 3-Axis vector magnets for Spintronic and neutron scattering or other experiments that require precise variation of the field direction relative to sample.
