SuperMag Systems by Janis Research Company SuperMag Systems To compliment the traditional variable temperature superconducting magnet systems, Janis Research has developed a set of optimized standard systems that combine the best cryostats, magnets and electronic components and thermometry available. These systems are designed to maximize the purchasing power of your budget, while offering the best available choice of thermometry and instrumentation. The systems available in this category offer environments from atmospheric pressure to ultra high vacuum, and temperatures that range from over 700 K to less than 10 mK. These are supplied with several choices of field independent thermometry, automatic temperature controllers, magnet power supplies, cryogen level and field monitors. Systems are also available with Lambda point refrigerators and 1 K pots, with LabView drivers and other software for computerized systems. Refrigerated systems are also offered for locations where liquid helium costs need to be minimized or completely eliminated.
Individualized attention is given to each request no matter how challenging the application.
They are available with optical access into the high field and low temperature region, with optional vacuum load locks that enable sample exchange without disrupting the main dewar and magnet. The field direction, magnitude and uniformity need to be specified, as well as the sample space required. These systems include field independent thermometry at the 1 K condensing pot, the internal He-3 charcoal pump and the low temperature sample stage. Other models include the MiniKelvin series with ultimate temperatures of less than 8 mK, and cooling powers of greater than 400 m Watts at 120 mK, the plastic DRP dilution refrigerators with sample in liquid, and the ultimate DRS series with lowest temperatures of less than 4 mK, and cooling powers of greater than 1,200 m Watts at 120 mK. Superconducting magnets with special cancellation coils that drop the field in the region of the mixing chambers, as well as carefully designed sample holders that practically eliminate eddy current heating, are included as part of the standard systems. Both high field magnets and split pair solenoids are available and special windows for specific types of electromagnetic radiation are included as required.
