Hall Scientific Limited is now offering Multi-axis Superconducting Magnets (Vector Magnets) from Cryomagnetics.

Cryomagnetics pioneered much of the work for multi-axis superconducting magnets and systems in the 1980s. Multi-axis superconducting magnets of all configurations have been manufactured for both end-users and OEM integrators alike over the years.

Recently, the popularity of multi-axis magnet systems has risen dramatically. Researchers benefit from the ease and precision of rotating magnetic fields instead of physically rotating the sample. Higher fields are now possible with larger vector sum angles than ever before.

Systems such as pictured on the left are cryogen-free. This system contained a 3-axis superconducting magnet assembly: • 5T in the Z-axis • 1T in the X-axis • 1T in the Y-axis.

As the world-leading manufacturer of superconducting magnets for gyrotron applications (gyrotron magnet systems typically have five superconducting magnets included for shaping field – a true challenge for multiple axis coils), Cryomagnetics has multiples of these successful installations worldwide.

Most gyrotron magnet systems have been cryogen-free since 2000, making Cryomagnetics the most experienced manufacturer of cryogen-free Multi-axis Superconducting Magnets systems.

In addition to manufacturing multi-axis superconducting magnets systems in room temperature bores as pictured above, we can also provide integrated VTI systems in both cryogen-free and traditional bucket dewar systems.
