With the use of a thinner monitor, a δλ mean / λ mean of ∼1% can be reached and with a modest increase of the distance between the reference monitor positions a δλ mean / λ mean of below 0.5% can be achieved. Further improvements are possible by using smaller chopper disc openings and a higher rotational speed chopper. The method requires only two neutron measurements and doesn't necessitate the use of crystals or complex fitting with sigmoid functions and multiple free variables, and could constitute a suitable addition to imaging, diffraction, reflectometers and small angle neutron scattering instruments, at spallation sources, that do not normally utilise fast choppers.]]> Tue 10 Oct 2023 14:46:18 AEDT ]]>
