A prototype neutron backscattering spectrometer using the GaAs 200 Bragg reflection has been developed to bring about a significant increase in energy resolution. The gain in resolution is offered by the narrow intrinsic line width of GaAs 200, an order of magnitude smaller than the line width of the currently used Si 111. Test measurements of the prototype on the backscattering spectrometer IN16B at the ILL have yielded an unprecedented energy resolution of δE = (76.5 ± 3.3) neV FWHM, a factor of 10 smaller than the current standard as well as a factor of 4 smaller than the highest currently available resolution in neutron backscattering. Further, the measurements have provided proof of concept for the construction of a full-scale user instrument.
