Title: Development of a Novel Piezo Driven Device for Fast Helicity Reversal Experiments on the XMaS Beamline

Abstract

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.
