Figure 5
TOF spectra for Ne at hν = 914 eV with 16 electron TOF spectrometers oriented perpendicular with respect to the X-ray beam. The spectra are the result of one single pulse from the SASE3 undulator. Red dashed lines indicate scattered light which defines the start time. Black dashed lines indicate the photoelectron lines 2s and 2p and also KLL Auger lines. The gray area indicates the 1s peak. The Ne 1s photoelectron has β = 2.00. The intensity distribution is dominating in the horizontal plane E and W and close to zero in the vertical direction N and S which indicates that the strongest component in the Stokes vector is the horizontal polarization. |
