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.
Group Leader, Senior Physicist/Argonne Distinguished Fellow
Zein-Eddine Meziani is aSenior Scientist and Group Leader of Medium Energy Physics in the Physics Division at Argonne National Laboratory. He is on leave from Temple University where he has served as a Professor of Physics since 1993. Dr. Meziani received his Ph.D. in 1984 from the University of Paris XI, Orsay, France in experimental nuclear physics. He then joined the Nuclear Physics at SLAC (NPAS) program as a postdoctoral fellow with the University of Virginia prior to joining the faculty of Stanford University as an Assistant Professor in 1986. He joined Temple University in 1993 as an Associate Professor and was appointed Professor in 1996.
Guy Savard is the Director of the ATLAS facility. In this role, he oversees the technical operation of the DOE National User Facility, its scientific program, and guides the evolution of the facility to keep on fulfilling the evolving needs of the US and international nuclear physics communities. He also leads the radioactive ion trapping group whose ion manipulation technique developments led to the CARIBU upgrade to ATLAS and the N=126 factory. He has a joint appointment with the Department of Physics and the Enrico Fermi Institute at the University of Chicago.
