Figure 6
Resolution function of the monochromator measured at 21.541 keV using nuclear resonant scattering from 151EuS. The resolution function is measured under normal operating conditions with a cooling-gas flow rate of 1.3 l s−1 (solid circles) and has a FWHM of 0.27 meV. The solid line is a shape function based upon two-beam dynamical diffraction. |
