Joe Arko was with the APS from its very first days. He worked in the Experimental Facilities Division and was one of most important contributors to the success of the APS undulator program and the first microfocusing beamline. In fact, Joe’s dedication and ingenuity gave life to one of the APS engineering marvels: undulator vacuum chambers. His “golden hands” created a multitude of magnetic sensors that played a crucial role in building the best APS undulators.
Subsequently, Joe supported the scientific instrumentations of the Microscopy and Imaging beamlines, where, in a constantly evolving technical environment, his creativity was essential to address every challenge, big or small, with a unique and elegant solution.
Joe worked at ANL for 41 years.
Joe enjoyed the interaction with people, and he was a great mentor for the junior staff. While with his professional dedication he touched many instruments, with his generosity and smile he touched all of us.
