P63 OperandoCat (under construction)

Combined XAFS/XRD measurements at P64 with two different operando cells.
Combined XAFS/XRD measurements at P64 with two different operando cells.

This quite complex experimental set-up combines x-ray diffraction measurements and x-ray absorption spectroscopy measurements with two different operando-cells. The measurements of the quartz-tube reactor required measurements only once an hour, while the measurements of the reaction in the electrochemical cell took just 45 minutes.

The XRD-data are collected with the large Eiger9M 2D-detector, while the XAFS-data are collected in transmission mode with conventional ion-chambers and a large-area PIPS-detector (not shown) in fluorescence mode.

This experiment was performed at P64, however, it is planned to do these kind of measurements regularly at P63.

P63 is a new beamline which will be dedicated to multi-modal operando measurements. It is designed and built in collaboration with the research group on Interface Science (Director Prof. Dr. Beatriz Roldan-Cuenya) from the Fritz-Haber Institut in Berlin, and the research group on Organic Spectroscopy (Director Prof. Dr. Serena DeBeer) at the Max-Planck-Institute for Chemical Energy Conversion in Mühlheim.

Right now, the specifications of critical components (monochromator, mirrors, undulator) are determined, and the preparation for the call for tender for the experimental hutch is underway.

The beamline is not in operation yet, and it is not possible to apply for beamtime as a general user for a few years.
