The experiment geometry. For every Laue spot on the pnCCD, a scattering vector is assigned. This vector is described either in the crystal frame through the Miller indices as or in the laboratory-frame coordinate system by the measured position and energy of the Laue spot. Angles (φ, θ, ψ) were used to correct the tilt of the detector frame (Xd,Yd,Zd) with respect to the laboratory frame (X,Y,Z). |
