Two types of diffractometer that have been constructed for surface X-ray diffraction experiments. (a) The (3+2)*1 diffractometer having three axes for the sample (φ, χ, ω), two for the detector (δ, γ) and one for the whole setup (α). (b) The (4+2) diffractometer having four axes for the sample (φ, κ, ω, ψ) and two for the detector (δ, η). |
