EMIL
Raytraced Beamline Performance Data
The optical performance of the EMIL beamline was intensively calculated with RAY [1].
The angular ranges of both PGMs are up to 15.3° for the mirror and 19.1° for the gratings. This allows for a wide operating energy range without grating change. At the standard cff-factor (2.25) the usable energy range is 70 – 2000 eV.
Figure 1 shows the estimated resolving power (left side) and photon flux at sample position (right side) for the UE48 soft X-ray beamline as a function of energy and cff-factor.
Figure 2 Calculated photon flux for UE48 soft and U17 hard X-ray beamline.
Figure 3 shows the calculated foci at the different given interaction points.
