A versatile, ultra-low background magnet for neutron scattering at SINQ

The increasing efforts in material science to create new and purpose tailored materials and the deeper understanding of the complexity of condensed matter represent a major driving force for science constantly pushing the limits towards extreme experimental conditions and towards experiments with higher degree of complexity. The ability to develop and build new sample environment setups enables novel experiments with neutron scattering instruments. We present a modern, compact split-pair cryomagnet which maximises neutron beam access avoiding support structures in the beam to minimise the background. It provides a large 50 mm diameter sample space in a compact outer diameter for magnetic fields of up to 10 Tesla. The system does not require a lambda-stage and allows fast ramping.
