Mirror Systems

This multi-layer monochromator uses a matched pair of multi-layers to select a relatively wide energy bandpass beam from a white beam source. For some experiments, the high energy resolution of perfect crystals is not required and the higher flux possible with multi-layers can reduce exposure times and speed data collection. The energy range of multi-layer monochromators can be from ~50eV to >20keV depending on the multi-layer design selected. The energy resolutions (ΔE/E) achieved are typically a few percent, but depend on the multi-layer design. Multi-stripe multi-layers can be supplied to give additional energy ranges. An optional lateral translation system enables a white beam bypass mode or permits the selection of multi-stripes depending on the orientation of the multi-layer mirrors.
