RIKEN SPring-8 Center FEL Physics Team
Team Leader: Takashi Tanaka (D.Eng.)
Research Summary
FEL physics team is in charge of development of devices called undulators, which induce interaction between radiation and electron beam to realize x-ray lasing. In addition, theoretical research and new XFEL scheme are explored to futher upgrade the laser performance of SACLA.
