|FEL experiments for atoms, molecules, and atomic clusters in the EUV to X ray regimes|
speaker : Prof. Kiyoshi Ueda[Tohoku Univ., Japan]
date : 2012-10-10
Following FLASH operation in Germany , SPring-8 Compact SASE Source (SCSS) test accel-erator in Japan  started user operation in 2008. These facilities provide EUVFEL pulses. In 2009, LCLS  started user operation. SACLA, Japanese XFEL , lased in June 2011 in the hard X-ray regime and started user operation in March 2012. We have been studying multi-photon processes in atoms, molecules, and clusters at these FEL facilities, from EUV to X-rays, using electron and ion momentum spectroscopy [5-17]. Also we have been performing pump-probe experiments, to probe the atomic motion in reaction, to see the evolution of nanoplasma formed by the FEL pulse, etc. During my talk, I will describe some showcase examples to illustrate how we enjoy new opportunities to investigate unexplored new areas of science using these new light sources.
