Accelerator Development Team

The team conducts R&D on accelerator components, such as an RF acceleration system, beam-diagnostics, an RF timing system for achieving ultimate performance of SASE FEL. The team also carries R&D out on components for Seeded FEL and a high-gradient and high-repetition linac.

Research Subjects

• Research and development on accelerator components for a Seeded Free Electron Laser.
• Research and development on a high-gradient and high-repetition linac.
• Femto-second resolution timing system development
• Nano-meter and femto-second resolutions beam monitor development
