Status of X-ray Free Electron Laser (XFEL) Projects and Applications

Dr. Yujong Kim

After successfully user services of short-wavelength Free Electron Laser (FEL) facilities at SPring-8 (SCSS) in Japan, DESY (FLASH) in Germany, and SLAC (LCLS) in USA, many laboratories around the world are  rushing to build their own X-ray FEL (XFEL) facilities, which can supply coherent, ultra-bright, and femtosecond (even atttosecond)
long hard X-rays. With advanced next generation X-rays, we can open femto-sciences in biology and chemistry and various new research fields in physics, structural biology, and material science where femtosecond temporal resolution and atomic-scale spatial resolution are required. During this talk, speaker will shortly introduce working principles of XFEL and superiorities of coherent XFEL over conventional incoherent X-rays. Then speaker will talk about current status of developing XFEL projects around the world and several applications of X-ray Free Electron Lasers.
