Project Description Objective: To provide a suite of accelerator testing facilities which can be utilised in partnership with industry, academic and scientific collaborators. Scope: The provision of a common high performance and flexible injector facility comprising an RF gun, associated RF power systems, beam diagnostics and manipulators, a high power photo-injector driver laser and associated enclosures. Costs: £2.5M capital direct from UK government has been assigned for this facility. This investment will be supplemented by £0.5M from STFC. Timescales: Project started August 2011, purchase the majority of the equipment in financial year 2011/12, with build in It is planned that first electrons from the facility are delivered in December
