Integration of the X-ray chopper system at the XTIP beamline. A spherical-grating monochromator (SGM) focuses the diffracted X-ray beam onto a moveable exit slit (EXS). The water-cooled zero-order slit (ZOS) removes unwanted diffraction orders and thus reduces the power load on the X-ray chopper. After vertical (V focus) and horizontal (H focus) focusing, the beam illuminates the tip/sample junction in the SX-STM endstation instrument. |
