We are mainly working on accelerator physics and technology.
1. Synchrotron radiation sources and advanced accelerators
2. Next-generation light source: Energy Recovery Linac (ERL)
3. Beam dynamics in accelerators
4. Design and development of state-of-the-art accelerator subsystems and components (magnet, vacuum, RF, monitor, control, insertion device and so on)
The recent activities are as follows:
(1) Design and R&D on Energy Recovery Linac(ERL): Beam dynamics, Injector, Superconducting RF cavity, Fiber laser for a photocathode gun, High-resolution monitor and so on.
(2) Study of novel insertion devices and the effects of their linear and non-linear fields on the beam.
(3) Study of new injection scheme using a pulsed sextupole magnet for top-up injection.
(4) Development of a new beam profile monitor using Fresnel zone plates in order to measure an extremely small beam size less than 10 microns (spatial resolution < 1 micron).
(5) Development of a fast orbit feedback system for beam position stabilization and study on a new orbit correction method uniting global and local orbit corrections for an efficient orbit feedback scheme.
(6) Development of a copper-coated vacuum chamber for reducing resistive-wall impedance under ultra-high vacuum to suppress wakefields and beam instabilities.
