Abstract

Multilayer gratings are important optical elements for obtaining a high efficiency high resolution performance in the soft x-ray region. Though the Mo/Si multilayer poses a poor thermal stability, it is a preferred combination for multilayer coating near the Si L edge region (λ=124Å). As a substitute to Mo/Si, a structure comprised of compound material NbC was proposed recently which exhibits superior thermal stability with identical reflectivity performance. In the present study, an analytical solution for grating efficiency calculation presented in Ref 2 by Kozhevnikov et al. is used to calculate theoretical performance of lamellar multilayer grating (LMG) comprised of Mo/Si and NbC/Si structure. Simulation results suggest that the performance of lamellar grating comprised of NbC/Si multilayer is identical with that obtained using Mo/Si multilayer grating.
