TL;DR: In this paper, the SPring-8 Angstrom Compact Free-Electron Laser (CFEL) was used for sub-angstrom fundamental-wavelength lasing at the Tokyo National Museum.
Journal ArticleDOI
High-gradient C-band linac for a compact x-ray free-electron laser facility
Takahiro Inagaki,Chikara Kondo,Hirokazu Maesaka,Takashi Ohshima,Yuji Otake,Tatsuyuki Sakurai,Katsutoshi Shirasawa,Tsumoru Shintake +7 more
TL;DR: In this paper, a C-band accelerator system has been developed and constructed for the compact x-ray FEL facility, SACLA, to fit within the available site length at SPring-8, and to reduce construction costs.
Journal ArticleDOI
Time-interleaved multienergy acceleration for an x-ray free-electron laser facility
Toru Hara,Kenji Tamasaku,Takao Asaka,Takahiro Inagaki,Yuichi Inubushi,Tetsuo Katayama,Chikara Kondo,Hirokazu Maesaka,Shinichi Matsubara,Takashi Ohshima,Yuji Otake,Tatsuyuki Sakurai,Takahiro Sato,Hitoshi Tanaka,Tadashi Togashi,Kazuaki Togawa,Kensuke Tono,Makina Yabashi,Tetsuya Ishikawa +18 more
TL;DR: In this paper, the authors proposed to deliver bunch-to-bunch energy changed electron beams at the end of the accelerator, which enables quasisimultaneous operation of multi-beam-line in the same undulator hall without degrading the stability and performance of the electron beam.
Journal ArticleDOI
Pulse-by-pulse multi-beam-line operation for x-ray free-electron lasers
Toru Hara,Kenji Fukami,Takahiro Inagaki,Hideaki Kawaguchi,Ryota Kinjo,Chikara Kondo,Yuji Otake,Yasuyuki Tajiri,Hideki Takebe,Kazuaki Togawa,Tatsuya Yoshino,Hitoshi Tanaka,Tetsuya Ishikawa +12 more
TL;DR: In this article, the authors measured coherent synchrotron radiation effects in multibeamline operation and reported the results of a multibase-line operation in a coherent manner.
Journal ArticleDOI
