New high-field actively shielded split-coil magnet for neutron scattering

Abstract

A new 16 T split-coil magnet system is being developed by Bruker BioSpin. This will represent the first high-field actively shielded split-coil magnet for neutron scattering experiments. The new magnet system will be installed at the Spallation Neutron Source (SNS) in the USA in 2009. The magnet is a symmetrical split coil, which can be operated in both symmetric and asymmetric field modes (for experiments with polarized neutrons).

Keywords:

We would like to thank SNS and PSI for this fruitful collaboration. In particular, we would like to thank Frank Klose and his team at SNS for the analysis of the neutron spin transport through the magnet system in asymmetric mode operation, and Peter Allenspach and his team at Paul Scherrer Institute for tests of materials and for important consultations. The Bruker team members are also strongly acknowledged.
