Spectral resolving powers according to (37) for focusing free of chromatic aberrations with CRLs depending on photon energy for the materials (from top to bottom) Li, Be, pmma, Si and Ni. The upper limit of the window corresponds to a value λ/Δλ = 7000, which is the intrinsic limitation for the resolving power of a double-crystal Si(111) monochromator. |
