3000 Gauss Superconducting Helmholtz Coil Magnet

Introducing a superconducting coil system in a Helmholtz pair geometry, offering high uniformity over the sample zone.

393 A9932 900x900

This HTS magnet system provides:

  • Higher steady-state field compared with Cu-coil Helmholtz pairs.
  • Large transverse access.
  • Very low fringe field.
  • Low weight.
  • Easy to operate, with a 3 kw input-power cryocooler.
  • High resolution bipolar magnet power supply.
