DLSITT1008 -Supply of Permanent Magnet Blocks and Metal Pole Pieces for CPMU-6

Located on the Harwell Science and Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. Diamond allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level.

To continue delivering the world-changing science that Diamond enables, the facility is being upgraded to Diamond-II, a co-ordinated programme of development that combines a major machine upgrade with new instruments and complementary improvements to optics, detectors, sample environment and delivery capabilities, and computing, as well as integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences.

The scope of the contract is

1. Manufacture, magnetization, characterisation, packing and supply of a set of (Nd0.2Pr0.8)2Fe14B permanent magnet blocks with dysprosium diffused into grain boundaries for enhanced stability.
2. Magnetic and dimensional measurements of the magnet blocks after manufacture and the supply of this data to DLS in machine readable (Microsoft excel or equivalent) format.
3. The coating and subsequent cleaning of the magnet blocks to ultra-high vacuum (UHV) standards
4. The manufacture and supply of a set of pole pieces. The material used should have a saturation magnetisation of at least 2.3 T, and it is the preference of DLS that Vanadium Permendur (or equivalent) is used.
