RIKEN SPring-8 Center

Accelerator Research and Development Group

Group Director: Hitoshi Tanaka (D.Eng.)
Hitoshi  Tanaka(D.Eng.)

The group conducts R&D on accelerator components, beam handling technology and insertion devices for achieving ultimate performance of SASE FEL. The group also carries out R&D on Seeded FEL that generates ideal brilliant X-rays having spatial and temporal coherence.

Research Subjects

  • Size reduction of XFEL system
  • High performance short period in-vacuum undulator
  • Innovative seeding system
  • Improvement of XFEL performance and operationability
  • Generation of highly brilliant electron beam
