Entering a new era: Possibilities for spectroscopy and diffraction experiments at the new POLAR beamline of the upgraded Advanced Photon Source

The recent completion of the upgrade has opened outstanding opportunities for the user community at the Advanced Photon Source at Argonne National Laboratory. The new low emittance x-ray source is now providing exceptionally brilliant and highly coherent beams, allowing for exciting experimental possibilities in scattering and spectroscopy in the hard x-ray range. POLAR, the beamline for polarization modulation spectroscopy at sector 4 of the APS, will utilize these intense focused beams with a high degree of coherence and tunable polarization. Researchers will have access to a variety of sample environments, such as for variable temperature, high magnetic fields, extreme pressures, and uniaxial strain, to combine with the beamline's advanced focusing capabilities and energy tunability. Additionally, the new beamline will enable dichroic ptychography and 3D dichroic tomography and allow for the investigation of magnetic domain ordering and electrically polarized structures in the sample bulk. In this presentation we will showcase some of the novel possibilities available at the beamline.
