Figure 1
X-ray profiles calculated using SRW at 70 m from the source with the slit at 35 m, for the ERL 5 m planar undulator with first harmonic at 3.6 keV, in high flux mode. Using 1 mm × 1 mm slits, fringes will appear [(a) two-dimensional image; (c) horizontal profile; (d) vertical profile]. With 1.5 mm × 1.5 mm slits, fringes will mostly disappear [(b) two-dimensional image; (e) horizontal profile; (f) vertical profile]. |
