ISIS pulsed neutron and muon source is a world-leading centre for research at the Science & Technology Facilities Council (STFC), Rutherford Appleton Laboratory near Oxford, in the UK. Our suite of neutron and muon instruments give unique insights into the properties of materials on the atomic scale.

Neutron choppers are essential components for the majority of the instruments for conditioning the neutron beam to enable a range of scientific techniques to be employed. Neutron disc choppers are spinning discs that block neutrons except for one or more window sections (openings) where the neutron beam is allowed to pass to the sample under study.

ISIS operates different types of disc choppers, and this tender request relates to two existing high speed double disc chopper systems that operate in a vacuum environment at a maximum speed of 18,000rpm. STFC is looking for a supplier of neutron cutting discs that will accommodate the existing choppers' interfaces and meet the operational requirements.
