Fluid Interfaces Grazing Angles ReflectOmeter

3D drawing of the instrument

No general view is available for this instrument since it is covered by 45 tons of lead.
A guide curved horizontally and vertically feeds neutrons to the instrument. There is a choice of two frame overlap mirrors which remove neutrons above specific wavelengths. A four-chopper assembly generates pulses with a choice of optimum flux or resolution. Two deflector mirrors direct the neutrons upwards or downwards towards the sample. A collimation guides focuses the beam in the horizontal plane. The sample position has a range of sample environments with many of them optimised for free liquid surfaces. An evactuated flight tube reduces air scattering after the sample. Lastly, a detector captures 2D images of neutron reflectivity.
