Description
- Designed for high heat load applications at XFELs
- Different use cases:
o Diamond zone plates
o Diamond gratings for spectral monitoring
o Split-and-delay schemes for ultra-fast pump-probe experiments
- Diamond zone plates allowing for peak power densities in the focal spot of 4x1017 W/cm2
- Combinable with the Ir-line-doubling technique
