11x-ray100CCDADSC QUANTUM 4Variable vertical and fixed horizontal slits. KOHZU double crystal monochromator with a water-cooled flat first crystal and a sagittally focused second crystal positioned for a fixed exit beam condition. Located ~18 m from source and ~6 m from sample position. Mirror system consisting of two vertically stacked, fused silica, spherical mirrors, to provide vertical focusing and harmonic rejection. One of the mirrors is rhodium coated and the other is uncoated. Located ~19.7 m from source.2006-11-15MSINGLE WAVELENGTH
