Optics: The beamline design follows the tried ALS two-stage focusing design (MacDowell et al., 2004). A vertically deflecting plane parabolic collimating mirror (M1) provides parallel light onto two sets of double-crystal monochromators (Si(111) and multilayer). A toroidal focusing mirror (M2) in the 2:1 position focuses the monochromatic X-ray beam onto a first focus spot in the hutch. This first focus spot is equipped with vertical and horizontal slits to create a virtual source. It also serves as the first experimental station (ES-1, high-pressure single crystal diffraction). Alternatively the virtual source can be re-imaged with a set of KB mirrors (demag 2.4(h) x 6.7 (v) onto the sample position of the second end-station (ES-2, high-pressure powder diffraction). More details can be found in beamline paper Kunz et al..
