Opportunity overview

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.
