Figure 3
Instrumental resolution as a function of scattering angle 2θ in the case of a powder with a grain size of 2r = 200 nm. The plots present the total instrumental resolution Σ with their contributions owing to geometry Δ(2θ)geo, bandwidth Δ(2θ)bw and grain size Δ(2θ)grain. The parameter set corresponds to the beam size in the far hall and L = 0.5 m. In (a) the natural bandwidth of the FEL was assumed. In (b) a bandwidth of ΔE/E = 10−4 was applied to take into account the bandwidth of a monochromator.
