Figure 1
(Left) A schematic representation of a moving monochromator crystal achieving an energy transfer in exact backscattering by a Bragg reflection in a moving reference frame, denoted a Doppler monochromator. [Adapted with permission from Hennig (2011BB55)]. (Right) A schematic diagram of a QENS spectrum. Depending on the velocity profile (cf. Fig. 2) of the Doppler monochromator, full QENS spectra (surface plot) or discrete energy transfers (red lines) can be acquired.
