Neutron Scattering

Neutron scattering has become an indispensable tool for probing the microscopic structure and dynamics over a broad range of length and time scales in quantum and magnetic materials.

By taking advantage of High Temperature Superconductors (HTS), HTS-110 has developed a range of superconducting magnet systems for neutron scattering which are used in worldwide neutron research facilities such as FRMII (Germany), ISIS (UK), ILL (France), NIST (USA) and ANSTO (Australia).

Key HTS Magnet features for Neutron Scattering

Cryogen-free with fast cool down
Room temperature bore or cold bore which can be integrated with variable sample temperature inserts
Higher operating temperatures allow faster ramping than conventional Low Temperature Superconducting (LTS) magnets
Passive or active shielding to minimize fringe fields
Rigid supports allow any field orientation
Asymmetric split-pair or Symmetric split-pair with passive shielding, with the possibility of tailoring the zero field node position for polarization analysis
Large room temperature apertures with no material in neutron beams to cause scattering background
Ability to be goniometer mounted for rotation
External zero-field nodes an option
