CLOSING TIME FOR BIDS IS 11/08/2017 14:00 HOURS. DO NOT APPLY DIRECTLY TO THE BUYER. To express your interest in this opportunity email ExpressionOfInterest@crowncommercial.gov.uk. To register on our e-sourcing portal click on https://gpsesourcing.cabinetoffice.gov.uk and follow the link "Supplier eSourcing Registration" The European Spallation Source (ESS) is a multidisciplinary research centre based on the world's most powerful neutron source and is currently under construction at Lund, Sweden. This new facility will be around 30 times brighter than today's leading facilities, enabling new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. As part of the UK in kind contribution to the ESS, STFC is responsible for delivering 88 high- SRF cavities capable of achieving 22.9 MV/m at 704 MHz, with a Q0 better than 5 x 109. Further technical background is available in section 4 and at https://europeanspallationsource.se/ The Niobium procured in this tender shall be used for the fabrication of the high beta cavities for the ESS project as above.
