Compact X-ray Free Electron Laser: Development and Applications
Prof. Arvinder Sandhu Arizona State University In this talk I will discuss the development of a Compact X-ray Free Electron Laser (CXFEL) at Arizona State University, with an emphasis on the underlying physics principles. CXFEL relies on the latest advances in accelerator and laser technology to produce a room-sized (roughly 10m long) X-ray laser with full coherence in time and space. The CXFEL will uniquely offer full control of the X-ray phase using electron-beam patterning that allows customized time-structure of the beam, e.g., attosecond pulses, very narrow linewidths, and precise timing between multiple pulses with different colors. We are also constructing multiple end-stations to perform femtosecond and attosecond x-ray spectroscopy and coincident attosecond momentum imaging in atomic and molecular systems. In the first phase of this project, we have successfully demonstrated the operation of a compact femtosecond hard-x-ray source based on the inverse Compton scattering process. Results from the commissioning of this ultrafast X-ray source, e.g. the X-ray diffraction studies in biochemical systems and quantum materials, will be highlighted.
