Schematic of the single-bounce monocapillary optics used for the slit-less design of the WDS (thick blue lines). It is characterized by its elliptical shape (gray dashed form) with the dimensions given in millimetres. To achieve focusing of the incoming beam, the width of the beam in the focusing direction must be larger than the exit radius of the capillary, which is 0.057 mm in this case. |
