Experimental set-up and diffraction geometry of the Weissenberg camera: PM, beam-position monitor; S, slit; M1, M2, mirrors; Mo, monochromator; IC, ionization chamber; C, crystal; Sc1, Sc2, screens; IP, image plate. The reciprocal lattice coordinates (x, y, z) can be described in the camera coordinate system (X, Y), where X is parallel to the direction of camera translation and Y is in the radial direction of the cylinder: x = cosνcosζ − cosζ, y = cosνsinξ, z = sinν − sinζ, X = D(tanν − tanζ) + (φ − φ1)/K, Y = Dξ. D = camera radius, K = coupling ratio of crystal rotation to camera translation, φ = crystal rotation angle from φ1 to φ2.
