Linear accelerators

Description

A next-generation light source test facility is to be constructed at the Daresbury Laboratory which will be known as CLARA (Compact Linear Accelerator for Research and Applications). The aim of the CLARA project is to develop a normal conducting test accelerator capable of generating longitudinally and transversely bright electron bunches and to use these bunches in the experimental production of stable, synchronised, ultra-short photon pulses of coherent light from a single pass FEL (Free Electron Laser) with techniques directly applicable to the future generation of light source facilities. UK Research and Innovation, Science and Technology Facilities Council requires a total of 8 RF windows for the CLARA facility. Each window must be capable of handling RF peak powers of up to 45 MW. All of these RF systems will be operated at a frequency of 2998.5 MHz with a pulse width of up to 3 μs and a repetition rate up to 400 Hz.

This specification concerns assisting in finalising the design, manufacture, and delivery to Daresbury Laboratory, of eight high power RF windows for the CLARA Linacs 2, 3 and 4 along with supporting documentation. The bid must comprise of: 1) High power RF vacuum windows; 2) Documentation; 3) Suitable gaskets; 4) Delivery to Daresbury Laboratory. All submissions will be assessed in accordance with the Public Contracts Regulations 2015, for procurement values that exceed Regulation 5 (Threshold amounts). This procurement will be managed electronically via the Crown Commercial Service’s e-Sourcing Suite. To participate in this procurement, participants shall first be registered on the e-Sourcing Suite. If bidders have not yet registered on the eSourcing Suite, this can be done online at https://gpsesourcing.cabinetoffice.gov.uk/emptoris by following the link ‘Supplier eSourcing Registration’. Please note that, to register, bidders must have a valid DUNS number (as provided by Dun and Bradstreet) for the organisation which you are registering, who will be entering into a contract if invited to do so. Note: registration may take some time please ensure that you allow a sufficient amount of time to register. Full instructions for registration and use of the system can be found at https://www.gov.uk/government/publications/esourcing-tool-guidance-for-suppliers. Once you have registered on the eSourcing Suite, a registered user can express an interest for a specific procurement. This is done by emailing ExpressionOfInterest@crowncommercial.gov.uk Your email must clearly state: — the name and Reference II.2.5) Award criteria for the procurement you wish to register for, — your organisations full name as a registered supplier, — the name and contact details for the registered individual sending the email. Crown Commercial Service (CCS) will process the email and then enable the bidder to access the procurement online via the e-Sourcing Suite. The registered user will receive a notification email to alert them once this has been done. As a user of the e-Sourcing Suite you will have access to emptoris email messaging service which facilitates all messages sent to you and from you in relation to any specific RFX event. Please note it is your responsibility to access these emails on a regular basis to ensure you have sight of all relevant information applicable to this opportunity.
