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 vacuum chambers for the beam pipe sections, which will predominately sit in the latter half of the accelerator. Scope of the contract The contract will cover the supply of materials, manufacture, inspection, cleaning, testing, vacuum firing, assembly, packing and subsequent delivery to Daresbury Laboratory, Warrington. The contractor will be required to co-operate closely with STFC Daresbury Laboratory (hereinafter referred to as STFC) and its authorised representative at all stages of the contract. Technical issues will be resolved after adequate discussion. Any detailed assembly drawings and calculations, tooling, fixtures and manufactured components constructed or otherwise procured under the terms of the contract will become the property of STFC to dispose of as it sees fit. The parameters of all detailed components and assemblies have been determined by STFC and are fully described in the accompanying drawings. The designs are the property of STFC and must not be disclosed to third parties without its express permission. The manufacturer will be responsible for any departure from anticipated performance due to the failure of the manufacturer to adhere to any part of this specification. No change to the specified designs is permitted without the written permission of STFC. However, if at any stage of the contract it is clear that advantage could be gained by such modification then the manufacturer is encouraged to bring it to the attention of STFC STFC reserve the right to amend the quantity required be it an increase or decrease of the items procured under this ITQ in order to satisfy the requirements of ESS.
