UK SBS PR19049 3T Horizontal Magnet

**Final date and time for the submission of bids is 16/10/2019 at 11:00 DO NOT apply directly to the buyer. All tender information MUST be submitted through the CCS eSourcing Portal.**

This requirement is for the design, manufacture, delivery and the installation of 3T Horizontal Magnet for the use at UK Research and Innovation(UKRI) - Science & Technology Facilities Council(STFC) - Rutherford Appleton Laboratory (RAL).

ISIS pulsed neutron and muon source is a world-leading centre for research at STFC - RAL near Oxford, in the UK. Its suite of neutron and muon instruments give unique insights into the properties of materials on the atomic scale.

Despite the great investment in building beamlines offering polarisation of the neutron beam, ISIS lacks sample environment optimised to exploit the full potential of the techniques. Until now, a set of room temperature electromagnets have been used in experiments requiring polarisation. These set of electromagnets offer a modest maximum field of 1.2 T perpendicular to the beam (even less if a cryostat needs to be added to the experiment) or 0.4 T parallel to the beam, and poor polarisation transport at low fields. This is a region of the utmost importance since most of the applications will work in absence or very small fields. Therefore for fully exploiting this appealing property of the neutron beams, ISIS needs to make an effort in expanding the available sample environment in order to provide larger fields and better polarisation transport at low fields.

Therefore a 3T horizontal magnet which transports the polarisation is required which will tackle both issues at once: it will multiply the maximum field by a factor or 2.5 (a factor 7.5 parallel to the beam), meaning that less experiments would have to be redesigned to accommodate the existing sample environment instead of the optimum scientific case; and the increase of the polarisation transport at low fields will allow the users to explore the regions closer to the working conditions for many prototype devices.

Detailed 3T Horizontal Magnet requirements are defined in the attached document,UK SBS PR19049 Specification.
