Accelerator Hardware Development Group
Innovative Synchrotron Radiation Facility Division,
RIKEN SPring-8 Center
(Group Director: Takahiro Inagaki )

Research Field

The Accelerator Hardware Development Group promotes the advancement of accelerator and light source systems and innovations in accelerator element technologies to improve the performance of the short-wavelength free electron laser (FEL) facility SACLA and the ring light source accelerator SPring-8. In order to improve the performance of the current SACLA, optimization of electron gun and injector parameters and system modifications will be investigated to achieve an effective low emittance electron beam. In the long term, we aim to realize a green and efficient XFEL at room temperature that can be highly repetitive and does not use superconducting technology using liquid He. For this purpose, we will vigorously research new acceleration methods, upgrade electron guns, acceleration tubes, and radio-frequency equipment, etc., as well as research and development using beam dynamics calculations and simulations based on the motion of charged particles in an electromagnetic field, which is necessary for the development of these systems.
