cryogen_free_magnet_vertical_3Cryomagnetics pioneered much of the work for multi-axis superconducting magnets and systems in the 1980’s. Multi-axis magnets of all configurations have been manufactured for both end-users and OEM integrators alike over the years.

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

Systems such as pictured at left are cryogen free. This particular 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 magnet systems.

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

Some of the more popular multi-axis magnet configurations include:

 

2-Axis 3-Axis
7T/2T (7 Tesla Z-Axis; 2 Tesla X-axis) 1T/1T/1T (1 Tesla Z-Axis; 1 Tesla X-axis; 1 Tesla Y-axis)
8T/2T (8 Tesla Z-Axis; 2 Tesla X-axis) 5T/1T/1T (5 Tesla Z-Axis; 1 Tesla X-axis; 1 Tesla Y-axis)
9T/1T (9 Tesla Z-Axis; 1 Tesla X-axis) 7T/1T/1T (7 Tesla Z-Axis; 1 Tesla X-axis; 1 Tesla Y-axis)
9T/4T (9 Tesla Z-Axis; 4 Tesla X-axis) 9T/1T/1T (9 Tesla Z-Axis; 1 Tesla X-axis; 1 Tesla Y-axis)
