Special systems for UHV compatible (scanning probe microscopy and other experiments) are available with a variety of magnetic fields.
Typical magnet configurations
- Split pair magnets with horizontal and vertical access
- Can be oriented with vertical or horizontal magnetic field direction
- Vector magnets enabling field direction to be adjusted in a 2D plane, or around a 3D sphere
ULT insert compatibility
These systems are supplied with He-3 or dilution refrigerator inserts.
The sample may be introduced through the top or the bottom of the cryostat or through a horizontal bore of a split pair magnet.
Many systems incorporate translation and rotation stages for sample loading, without needing to warm-up the magnet cryostat.
Please feel free to contact JanisULT to discuss your requirement.
Ultra High Vacuum (UHV) Compatible Long Hold Time Superconducting Magnet System
JanisULT is pleased to offer a UHV compatible long hold time He-3 superconducting magnet system. It offers a hold time in excess of three days, at a temperature of less than 0.3 K, with no active pumping on the 1 K pot. The cryostat includes two magnets with a guaranteed 8.5 T vertical field and a 0.8 T horizontal field, with persistent current switches on both magnets.
The system also includes a 12" translation stage that allows translation of the sample out of the magnet bore for sample installation and replacement in the cold UHV environment
