Simulations of the resolving power of the AGM for the entrance slit widths of 2, 5 and 10 µm and the exit width of 3 µm. The resolving power is defined as , where E is the photon energy and ΔE is the energy resolution. All simulations were performed with = 174°, r1 = 3.5 m, r2 = 2.5 m, n0 = 1200 grooves mm−1, n1 = 0.8 grooves mm−2 and slope error = 0.25 µrad r.m.s. |
