Temperature distribution (top) and thermal slope (bottom) at 2 keV. To achieve an efficient photon flux transmission at the second DCM crystal, the slope error on the first crystal should be a fraction of the rocking curve width, which for Si(111) at 2 keV is 918 µrad. Based on an integrated reflectivity of 99%, the allowable maximum slope error was calculated to be 45.9 µrad. The slope error is acceptable in a sense that there would be no significant transmission intensity losses. |
