“…Monte Carlo simulations estimate a degree of circular polarization of 0.7 for the parameters used: 2 mm beam height and 2 mm vertical offset to the orbital plane of the storage ring. 13,14 The x rays were monochromatized by a germanium ͑311͒ double crystal, and the Bragg angle for the required energy degrades the degree of circular polarization by an additional factor of 0.4 due to the semiempirical relation…”

Magnetic circular dichroism is observed for ferromagnetic EuO (T C ϭ69 K) in the ␤ 2,15 fluorescence at incident photon energies resonant with the 2p 3/2 excitation. The dichroism is dominated by exchange interaction between the localized 4 f electrons and the final state 4d core hole. The spectral shapes obtained by atomic multiplet calculations for the 2p4d emission show good agreement with the experimental data.

Synchrotron radiation facilities provide highly polarized x-ray beams across a wide energy range. However, the exact type and degree of polarization vary according to the beamline and experimental setup. To accurately determine the angle and degree of linear polarization, a portable x-ray polarimeter has been developed. This setup consists of a silicon drift detector that rotates around a target made of high-density polyethylene. The imprint generated in the angular distribution of scattered photons from the target at a 90-degree angle between the incident x-rays and detector has been exploited to determine the beam polarization. Measurements were conducted at the GALAXIES beamline of the SOLEIL synchrotron. The expected angular distribution of the scattered photons for a given beam polarization was obtained through simulations using the Geant4 simulation toolkit. An excellent agreement between simulations and the collected data has been obtained, validating the setup and enabling a precise determination of the beam polarization.
