UK SBS PR20035 CLARA X-band High Power RF Window

The final date and time for the submission of bids is 14/07/2020 at 11:00 BST. DO NOT apply directly to the buyer. All tender information MUST be submitted through the Delta eSourcing Portal. Brief Description of Requirement A next-generation light source test facility is to be constructed at the Science and Technology Facilities Council's (STFC) 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. The Fourth Harmonic Cavity (also called X-band lineariser) of the CLARA facility is an RF cavity operating at 11994 MHz. The cavity will be powered by a 8-10 MW klystron that is pulsed at a repetition rate of 100 Hz with a pulse length of up to 2.5 μs. This pulse will be compressed using a SLED I type RF pulse compressor to 120 ns and a maximum power of 30 MW. This specification concerns the manufacture and delivery to Daresbury Laboratory of the high power RF window requirements for the Fourth Harmonic cavity consisting of: 1. 2 X-band high power RF windows 2. Copper coated International Universal WR90 vacuum flanges brazed to window 3. Delivery to Daresbury Laboratory, Keckwick Lane, Daresbury, Warrington WA4 4AD, United Kingdom.
