Simulated experiment The polychromatic neutron beam from the hot neutron beam tube H8 is diffracted by the monochromator, where a single wavelength is selected. The diffracted beam passes through a filter ... sample: usually a gas, a liquid, an amorphous or a powdered material. The intensity of the scattered neutrons is measured by an array of nine ...

through a Be filter and arrives at the supermirror bender polariser. The neutrons are polarised in the z-direction. The neutrons pass through a Mezei spin-flipper, which is "off" when measuring non-spin-flip ... cross-sections. The neutrons are rotated into the x, y or z direction using 3 orthogonal Helmotz coils situated at the sample position. ...

Simulated experiment The polychromatic beam from the hot neutron tube H3 arrives at the monochromator. The monochromatic diffracted beam reaches the sample – a single crystal - located at the centre of

or selects a beam of neutrons in a narrow energy band. The analyser is positioned to select a scattering direction (related to the momentum transfer, Q) The energy of the neutrons which pass through the

desired neutron wavelength by Bragg’s Law. The reflected monochromatic beam then passes to the Fermi chopper, effectively a rotating collimator, which only transmits neutrons when the neutron path is parallel ... Simulated experiment A polychromatic (white), neutron beam is partially monochromatised by the two counter-rotating disc choppers, ...

Simulated experiment A principle of a neutron Laue diffractometer is extremely simple. When a single crystal is placed in a white beam it diffracts neutrons in many directions. The diffracted beams which

Simulated TAS experiment The animation shows the principle of a neutron inelastic scattering experiment with IN20 by means of the classical three axis spectrometry (TAS). The polychromatic beam from the
