Abstract
On June 11, 2002, a meeting was held at Milton Hill near the Rutherford Appleton Laboratory to discuss the MERLIN project with the user community. The project started in February 2002 with an official announcement that EPSRC was to fund the construction of the MERLIN chopper spectrometer at ISIS through grants to Keith McEwen (UCL), Stephen Hayden (Bristol), and Martin Dove (Cambridge). MERLIN is designed to be a high intensity, medium energy resolution spectrometer, using supermirror guides to provide a high neutron flux onto the sample. Position sensitive gas detectors, like those used on MAPS, will be used to provide more than JC steradians of solid angle coverage with an angular range from −45° to 135° in the horizontal plane and ±30° in the vertical plane. This will allow large swathes of q,ω space to be accessed simultaneously.
