Sacla: In-Vacuum Variable-Gap Undulators (About 130 m Long)

Caption

A team working at the SACLA X-ray Free-Electron Laser in Japan has succeeded in generating ultra-bright, two-color X-ray laser pulses, for the first time in the hard X-ray region. These light pulses with different wavelengths, whose time separation can be adjusted with attosecond accuracy, are very powerful tools to investigate the structure of matter and the dynamics of ultrafast physical processes and chemical reactions.
