Figure 7
Symbols: measured horizontal FWHM of the central peak as a function of calibrated slit width, at 12.0 and 22.1 keV, for slits B. At 22.1 keV, data were measured for two values (0 and 10 W) of heating power on the beamline horizontal mirror. Curves: calculated FWHM, for best-fit incident divergences given in Table 1 ![]() |
