Theoretical parasitic count rate per speckle for a 5.6 µm-diameter pinhole (dashed) and a two-dimensional Pt aperture with θ = 80° and Δeffx = Δeffy = 5 µm at 8 keV. For the Pt aperture, two scans are shown, one along a direction parallel to the diagonal of the aperture (solid), and one along the direction of the blade motion (dotted). |
