The Lake Shore DryMag is a cryogen-free superconducting magnet system designed for operation at temperatures as low as 1.5 K, with an optional He-3 insert allowing for temperatures down to 300 mK. It provides horizontal magnetic fields up to 7 T for optical applications and vertical fields up to 12 T for non-optical applications. The system features a top-loading sample positioner that allows for easy sample exchange without warming the cryocooler, significantly reducing turnaround time. The sample can be rotated on a vertical axis, and the system operates in a static helium exchange gas environment, which is beneficial for studying poorly thermal conducting samples. The DryMag includes a two-stage GM mechanical refrigerator with a cooling power of at least 1.0 W at 4.2 K, and it is equipped with a Lake Shore 625 ultra-high stability power supply capable of delivering up to 60 A. The system also features calibrated Cernox temperature sensors, non-magnetic heaters, and a Lake Shore 336 temperature controller for precise temperature management. Optional accessories include electrical feedthroughs for measurements and an integrated electrical transport measurements package for automated magnetoelectrical measurements. The DryMag is suitable for a variety of research applications, including studies of electronic properties of materials and magneto-optical experiments.
We are 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.
Cryogen-free 1.5 K superconducting magnet system
The standard DryMag product line has a fully integrated variable temperature insert with sample in static exchange gas, for operation from below 2 K to as high as 420 K. An optional He-3 insert allows access to temperatures as low as 300 mK. Our room temperature bore cryogen-free magnet systems can also be combined with a microscopy cryostat. Cryogen-free magnet systems are available to investigate a large variety of research studies such as quantum Hall effect, quantum dots, Mössbauer spectroscopy, magneto-optical experiments, plus many others.
