In April of 2023 P61A, the White Beam Materials Science Beamline operated by Hereon at PETRA III, completes two years of user operation. The beamline makes use of the unprecedented high intensity and high energy wide spectrum beam delivered by the 10 wigglers in the PETRA III north hall straight section, containing usable flux from 20 keV to 200 keV. Such a remarkable beam allows for a myriad of experiments ranging in areas from medical sciences to chemical synthesis, but its power is unique when used in materials science experiments with energy dispersive diffraction (EDD). Particularly, the EDD measurement geometry with a high energy beam grants unique versatility for bulk experiments, removing the need for downsizing samples or adapting sample environments for beam clearance.

This talk will describe the P61A experimental station, and give a summary of its user demand so far. Additionally, some experiments will be highlighted, showing the instrument’s potential in property mapping in complex samples and in-situ measurements of manufacturing processes. The talk will conclude with an outlook of the beamline’s future, including currently planned developments.
