Figure 2
Vertical undulator beam profile measured through a 0.27 mm-diameter pinhole at an energy E = 7.26 keV detuned from the first harmonic energy of E = 7.66 keV. (a) Profile before X-ray-beam steering corrections. The cut-offs at about ±1.5 mm are the shadow of an upstream 3 mm-diameter aperture. (b) Profile after a 15 µrad vertical steering correction down. The local minimum in the profile is now centred in the 3 mm-diameter aperture.
