Figure 22
Black lines are the flux of the monochromatic beam measured at the sample position for a full spot size, plotted as a function of X-ray energy for an electron beam current of 500 mA and 2.8 T source. Diamonds are related to measurement made with the Si(111) monochromator whereas circles relate to measurements carried out with the Si(220) monochromator. For comparison purposes, the flux measured at the sample position for the 1.7 T source and Si(220) monochromator (gray dotted lines) is reported as well as the flux calculated for perfect optics using the 2.8 T Superbend (red lines). |
