Description
Photon Science and Particle Physics and Astrophysics, and Applied Physics at Stanford University and SLAC
The invention of ultrafast light sources has opened a new window into the physical world, enabling the observation of nature at the characteristic time and length scales of atomic phenomena. Ultrafast techniques have inspired new fields of research in physics, chemistry and material science, and have been recognized twice by the Nobel prize committee in the last decade.
The x-ray free-electron laser (XFEL) is the most advanced source of x-rays available, with a peak brightness that surpasses traditional synchrotron sources by ten orders of magnitude. XFELs have recently broken the femtosecond and Terawatt limits, opening a new chapter for attosecond science.
In my talk I will give an overview of the physics of XFELs and their scientific applications. I will then focus on the recent development of attosecond XFELs and their use in the study of electronic phenomena in matter. Finally, I will discuss my views on the future of our field, combining XFELs with new technologies such as plasma-based accelerators and x-ray optical cavities.
Bio: Ago Marinelli is an assistant professor of Photon Science and Particle Physics and Astrophysics, and, by courtesy, of Applied Physics at Stanford University and SLAC. He received his PhD in Physics in 2012 from UCLA and moved to SLAC shortly after as a research associate. He was awarded a Panofsky Fellowship in 2015 and joined the SLAC faculty in 2019. He currently leads the FEL R&D program at the LCLS and the FEL physics department in the Accelerator Research Division.
