Light Source Division operates two storage rings at the Photon Factory (PF and PF-AR), which is a pioneer of synchrotron light sources in the world. It also performs R&D for an Energy Recovery Linac (ERL) as a future light source.
We are studying about the beam orbit in the storage ring, and conducting research and development on the related component such as DC electromagnet and its power source, pulsed electromagnet for beam injection and its power source and so on. For the future light source (ERL), we are doing research and development about the lattice design, beam dynamics including bunch compression, the advanced electromagnetic system aimed at stable beam orbit.

We are conducting research and development on the cavities, high-power klystron, high-voltage power supplies and low-power RF control system of the storage ring. For the future light source (ERL), we are doing research and development on the buncher cavities and studying a beam instability associated with a higher-order mode and ion trapping.

We are improving and maintaining the vacuum system and the superconducting wiggler. We are also conducting research and development on the vacuum system related with a replacement of new-type monitoring systems and insertion devices. As a result of these R&D, beam instabilities are restrained and storage of electron beam with higher current, longer lifetime and higher stability become possible. We are doing research and development about advanced vacuum systems for the future light source (ERL).

We are conducting research and development on the high-precision monitor system of electron and photon beam in the storage ring. We are also doing development of a control systems and feedback systems for the effective operation of the storage ring, and maintenance and improvement of related apparatus. We are also doing development and construction of a high-speed feedback system to prevent beam instability. For the future light source (ERL), we are dealing with R&D of an advanced beam diagnosis system which can be detect of high-current, extremely short bunch and super-low emittance beam.
