The high-performance dual-band multilayer coatings we propose to develop will enable the construction of EUV imaging and spectroscopy instruments having higher collection efficiency, lower mass and volume, and lower cost than is currently possible using conventional multilayer coatings. Our proposed new dual-band multilayer coatings will thus meet the performance requirements of future NASA solar missions such as FACTS, RAM, Solar-C and others that will need even higher cadence, lower signal-to-noise, and higher angular and spectral resolution. High-performance dual-band EUV multilayers will find application in a variety of other areas of research, including plasma diagnostics, high-harmonic generation sources, X-ray lasers, and other emerging EUV applications.
