(a) Calculated on-axis X-ray intensity and Stokes parameter P3 = S3/S0 (ellipticity) as a function of the radiator's shift parameter for hν = 700 eV in the third harmonic and footprints of the monochromatic beam 10 m from the source at different polarization states (images calculated with WAVE; Scheer, 2012). (b) Calculated emission cone (with SRW; Chubar & Elleaume, 1998) at 10 m from the source for horizontal (red) and vertical ellipses (black). The beam is horizontally much narrower for the vertical elliptical case (at a shift of ∼24.5 mm). |
