Figure 9
Vertical angular distributions of the intensity transmitted by the front-end as a function of energy and the degree of circular polarization (contour plots) in the configuration removing the horizontal aberrations up to and including the spherical term. The empty area in the center of the image results from the slit in the first M1 mirror that allows hard X-rays to pass through. The low level of beam aberrations allows, for CD experiments, well defined vertical transversal areas where the beam is both intense and highly circularly polarized. LCP: left circularly polarized light. RCP: right circularly polarized light. |
