Electric motors, generators and transformers

Description

This requirement is concerned with the design, manufacture, testing, documentation, and delivery of DC Power Supplies for Riken Beamline Upgrade for the use at the ISIS Facility at STFC RAL, full details of which are contained in the UK SBS PR19087 specification document (and any other associated documentation). This requirement is concerned with the design, manufacture, testing, documentation, and delivery of DC Power Supplies for Riken Beamline Upgrade for the use at the ISIS Facility at STFC RAL, full details of which are contained in the UK SBS PR19087 Specification document (and any other associated documentation). The ISIS Facility at STFC Rutherford Appleton Laboratory(RAL) is the world’s most productive pulsed neutron source. In addition to producing neutrons, ISIS is also the world's most intense source of pulsed muons for studies in materials science. These Muons are delivered to the individual experimentation areas by means of an evacuated beam pipe leading from the intermediate target. The Muon beam is bent and kept centrally located by means of bending dipole magnets and quadrupole magnets. Helmholz coils are then used in the experimental areas. DC power supplies are used for energising the quadrupole magnets, bending magnets and Helmholz coils (both longitudinal and transverse), installed on the Riken beamline which forms part of the ISIS facility. The Riken experimental beamline was constructed in the early 1990’s. Many of its components date from the original construction and whilst have proven reliable are now overdue for replacement or refurbishment. The DC power supplies need to be replaced with modern efficient units which can be maintained easily and use current componentry. This will enable the beamline to operate with greater stability and repeatability and thus enhance the facility. The requirement consists of procuring four main types of Power Supplies named as Quadrupoles, Argus, Chronus and RB2 to replace all obsolete power supplies in Riken beamline. The minimum number of units to be procured is 20 units with an option of procuring additional 12 quadrupoles making the total 32 units.
