Title: Fast helicity switching of x-ray circular polarization at beamline P09 at PETRA III

Abstract

At the resonant scattering and diffraction beamline P09 at PETRA III/DESY, polarization manipulation in the X-ray energy range 3-13 keV is possible using wave-plates. Recently, fast flipping of circular polarization helicity using the Raspberry Pi controlled FPGA (PiLC) device developed at DESY and dedicated piezo-electric flippers has been commissioned. Functionality of the PiLC for XMCD and first XMCD measurements at the Fe K-and Dy-L{sub 3} absorption edges are presented.

  • The first XUV beamline (200-2000 eV) at NSLS-II will have two branches, one optimized for photon hungry experiments requiring high coherent flux and one optimized for studies of polarization sensitive materials and interfaces based on fast polarization switching. We describe here the branch designed for fast polarization switching with frequencies up to 1 kHz, high photon flux, and good energy resolution. The beamline will be served by two canted undulators and is based on the focusing variable line spacing grating monochromator. The two beams will be focused at the same spot of approximately 80x10 {mu}m (hor.xver.). The expected circular polarizedmore » flux at the sample from each device up to 1.4 keV will be higher than 10{sup 12} photons/s at a resolving power better than 10{sup 4}. An additional KB focusing system will deliver the two beams to a spot in the {mu}m range.« less
  • A measurement system for circular dichroism (CD) of soft X-ray absorption has been developed using helicity switching of circularly polarized radiation by twin helical undulators at BL25SU of SPring-8. Difference of horizontal spot positions between the negative- and positive-helicity light at the sample position is within {+-}3{mu}m. Measurement time for magnetic circular dichroism (MCD) of core absorption is shortened to less than 1/3 in comparison with an existing system of magnetic field switching, keeping the same data quality.
  • The XMaS diamond phase retarder has been combined with a phase sensitive detection method to probe weak signals buried in high backgrounds. The system was tested in x-ray magnetic circular dichroism (XMCD) studies. Fast reversal of the photon helicity was effected by a new piezo driven device operating at 10Hz and higher frequencies. The XMCD signal was detected through the use of a lock-in amplifier. This technique was successfully applied at the L2 and L3 edges of a GdCo2 foil.
  • A transmission-type circular polarimeter has been developed for the magnetic Compton-scattering experiment. With this device, it is possible to non-destructively monitor the approximate value of the degree of circular polarization of incident x rays during an experiment at intervals of, e.g., a few minutes.
  • Twin helical undulators and five kicker magnets have been installed in the 5 m straight section of SPring-8 BL25SU to provide helicity switched circularly polarized radiation in soft X-rays. Helicity of circular polarization is changed by means of electron beam orbit bumps. We successfully increased frequency up to 10 Hz without disturbing the stability of the electron beam orbit.
