MAGNET SPECIFICATION FOR THE DARESBURY LABORATORY ERL PROTOTYPE

Daresbury Laboratory has funding for the design and construction of an Energy Recovery Linac (ERL) prototype, to facilitate the research and development necessary for the 4th Generation Light Source (4GLS). In the prototype a 35MeV electron beam will be used to drive an infra-red oscillator free-electron laser (FEL). A number of pre-existing magnets are being used in the layout, so new magnets are being procured, ensuring compatibility with the existing units. This paper gives an overview of the magnet requirements for the facility and details of the engineering realisation and procurement strategy.
