UKSBSPR17157 Fabrication and Treatment of High Beta Cavities

Tender description

CLOSING DATE FOR SUBMISSION OF BIDS IS 19th MARCH 2018 14:00PM (GMT) PLEASE DONT CONTACT THE BUYER DIRECTLY The mandate of the European Spallation Source ERIC is to design, plan, construct, commission, operate and decommission the European Spallation Source (ESS). It is located in Lund, Sweden, co-hosted by Sweden and Denmark and has more than 17 Partner Countries, including the UK. The UK contribution is coordinated by STFC. The facility will deliver its first neutrons in 2019 and is expected to be fully operational by 2025. The European Spallation Source (ESS) will be one of the largest infrastructures in Europe and will be used for neutron production for materials research. It will use a long pulsed superconducting linac and accelerate a 62.5 mA proton beam current to the energy of 2000 MeV. Peak beam power to the target will be 125 MW, 7 times more than the highest power existing facility. STFC are providing a number of goods and services on behalf of the ESS. This tender is for the purchase of the superconducting cavities of the high-β section at 704.42 MHz of the proton LINAC for the European Spallation Source (ESS). Cavities are equipped with the He-tank and will be produced ready to be RF tested at a qualified laboratory. STFC will provide all high purity Niobium materials to produce the piece parts.
