Bob O Hettel

Project Director, Advanced Photon Source Upgrade


Robert Hettel is the Project Director of the Advanced Photon Source (APS) Upgrade at Argonne. Hettel will oversee the planning, construction, and implementation  of the upgrade. The APS is a DOE Office of Science User Facility. This $815 million project will create the world’s most advanced three-dimensional hard X-ray microscope and enable researchers to view and manipulate matter at the atomic level to solve complex science problems across multiple disciplines.

Hettel has served in numerous accelerator design and leadership roles, helping  to develop technologies to advance light source performance.

He is a veteran accelerator designer and expert on storage-ring light sources, coming to Argonne in November 2017 from the SLAC National Accelerator Laboratory, a U.S. Department of Energy Office of Science Laboratory that includes the Stanford Synchrotron Radiation Lightsource (SSRL), a DOE Office of Science User Facility.

Hettel served as Deputy Associate Lab Director for Accelerators at SLAC. In 2013, he became the acting Head of the Accelerator Research Division, a division that pursues research and development in beam physics and technology for free electron lasers, colliders, storage ring and compact light sources, and advanced-technique accelerators. In this role, Hettel helped launch the ultra-fast electron diffraction and microscopy program that is now underway at SLAC.

Hettel earned his B.S. in physics with departmental honors from Harvey Mudd College in Claremont, California. He has benefited from decades of training in accelerator science and technology from many distinguished mentors at SLAC  and elsewhere. In 2010, Hettel was promoted to the Distinguished Staff at SLAC.
