Schematic view of the set-up. The diffracting plane (y, z) containing the Rowland circle is vertical, normal to the horizontal incident beam (the angular domain covered by this single crystal ranges from 84 to 96° with respect to the incident X-rays). The energy selectivity is performed with two linear motions along the y and z axes which allow the θBragg,CAS angle to be changed keeping the bent crystal on the Rowland circle. The two angular motions, γ and δθ, allow a precise alignment of the crystal (position with respect to the y axis and verticality). Inset: schematic drawing of the crystal analyzer positioning.
