Summary of the contracting process

The public procurement process for the UKRI-5692 tender, led by UK Research & Innovation (UKRI), involves the development and installation of the MUSHROOM and WISH II neutron guides. These optical and precision instruments are intended for the ISIS Neutron and Muon Source facility in Oxfordshire, United Kingdom. The tender, adhering to an open procurement method, reached the contract award stage on 8th May 2026, following its initial announcement on 25th February 2026. The contract, completed with a gross value of £2,029,584, engages SwissNeutronics AG as the supplier. The procurement falls under the 'Laboratory, optical and precision equipments' category, with key project milestones including the contract's commencement on 29th May 2026 and conclusion by 31st October 2027.

This procurement presents significant opportunities for businesses in the laboratory and precision equipment sector, especially those involved in the design and installation of neutron guides. The open procedure allows for broad competition, encouraging innovation and value in the bids. While SwissNeutronics AG, a large-scale company, has been awarded the contract, the invitation to tender had also been suitable for SMEs capable of delivering on both quality and price, with quality holding a substantial weight in the evaluation criteria at 70%. Businesses with expertise in high-precision instrumentation, and experience in significant public projects, would find such tenders ideal for expanding their portfolio and market presence.

Notice Title

UKRI-5692 ISIS MUSHROOM/WISH-II Neutron Guides

Notice Description

This Tender specifies the requirements for the supply of the MUSHROOM and WISH II neutron guides. Both are to be supplied under this contract. The guides will be installed at the ISIS Neutron and Muon Source facility in Oxfordshire. ISIS uses neutrons produced via spallation in a variety of beamlines to investigate material properties and life sciences. The MUSHROOM instrument project will deliver a new instrument to be used for indirect spectrometry located on Target Station 2, port W8.. The WISH-II instrument will deliver a cold neutron diffractometer located on Target Station 2, port E9. The requirement is to design, supply, install, test and align (approximately 37.1m for MUSHROOM and 33.3m for WISH II) of straight, elliptical neutron guide with the M-values and reflectivity described in the Tender documents, and the associated housings and supports. Please refer to the two technical specifications and ITT documentation for the full suite of requirements.
