Abstract
The single shot damage thresholds of multilayer optics for highintensity short-wavelength radiation sources are theoretically investigated,
using a model developed on the basis of experimental data obtained at the
FLASH and LCLS free electron lasers. We compare the radiation hardness
of commonly used multilayer optics and propose new material
combinations selected for a high damage threshold. Our study demonstrates
that the damage thresholds of multilayer optics can vary over a large range
of incidence fluences and can be as high as several hundreds of mJ/cm
This strongly suggests that multilayer mirrors are serious candidates for
damage resistant optics. Especially, multilayer optics based on Li2O spacers
are very promising for use in current and future short-wavelength radiation
sources.
