John Byrd is the Director of the Accelerator Systems Division at the Advanced Photon Source and Director of the Argonne Accelerator Institute. He supports the continuous improvement in performance, capability, and reliability of the Advanced Photon Source as well as guiding future directions for accelerator development at Argonne. John received his doctorate in accelerator physics from Cornell University in 1991. He is a Fellow of the American Physical Society. 

Sergey Chemerisov is the Manager of the Intermediate Voltage Electron Microscope (IVEM) and Low Energy Accelerator Facilities (LEAF) in the Experimental Operations and Facilities division at Argonne National Laboratory. His experience includes electron paramagnetic spectroscopy; radiation chemistry of water in confined media; development of high-intensity positron sources; radiation chemistry of fissioning solution; development of novel ways for producing radioisotopes; development of high-power beam targets; and managing accelerator upgrades, operations, and maintenance.

I have worked in accelerator development in the Physics Division at Argonne National Laboratory since 1999, in large part supporting our group’s decades long aim to develop world leading technology for superconducting ion accelerators, such as ATLAS, and for other U.S. DOE accelerators. Particle accelerators are, of course, among the most important tools enabling discovery science within the DOE and are increasingly important in areas such as medicine and the environment. As a postdoc, I led the effort to develop Argonne’s first systems to process, clean and assemble modern low-beta superconducting cavities. Much of my time at Argonne has focused on the development new SRF structures to bridge the velocity region between early low-beta cavities and elliptical cell cavities for electron accelerators. I served as the principal investigator for SRF activities at Argonne for the International Linear Collider (ILC). Recent work includes the development of a unique SRF system for bunch lengthening at the Advanced Photon Source to increase the lifetime of the electron beam. Through ongoing support from DOE we aim to develop transformative and next generation niobium-tin cavities for future ion accelerators.

John Power is the Accelerator Physics Group Leader within Argonne’s High Energy Physics division. His interests are in theoretical, experimental and simulation research of structure and plasma wakefield acceleration, phase space manipulation, photoinjector sources, RF linac/guns, and electron beam diagnostics carried out at the Argonne Wakefield Accelerator (AWA) facility.
