Description
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 subject of this call for tender are the power converters for the Booster BF and quadrupole magnets as indicated below.
BF
Number of Magnets: 36
Connection Arrangement: Series
Number of Power Converters: 1
Quadrupole
Number of Magnets: 4 per converter
Connection Arrangement: Series
Number of Power Converters: 5
The solution foreseen for both types of power converters is two quadrant H-Bridges fed from a DC bus/capacitor. The voltage on the capacitor is controlled by a boost regulator fed from an AC/DC SMPS, as shown in Diagrams 1 and 2. This has the advantage of presenting a fairly constant load to the ac distribution system, with energy circulating between the DC bus capacitor bank and magnets. The Booster Quadrupole power converters could have a common DC bus/capacitor and AC/DC SMPS. The contractor may propose an alternative arrangement. There will be three variants of the Booster Quadrupole power converters. They will all have the same power circuit, but two variants will have reduced current control ranges to achieve greater repeatability, resolution, and stability. This will be achieved by fitting different DCCTs and/or current sense resistors.
