Beamline Optics
The first optical element of the beamline, a tangential cylindrical mirror, deflects and collimates the beam horizontally. The Variable Line Spaced Plane Grating Monochromator (VLS-PGM) is equipped with four VLS gratings to cover the designed energy range of the beamline. The monochromatic light is focused on the exit slit, and then re-focused at the sample position by selecting one of two toroidal mirrors depending on which beamline branch is in use.
