Norio Nakamura is a professor emeritus and researcher in accelerator-based light sources at High Energy Accelerator Research Organization (KEK), where he was a professor and leader of the beam dynamics and magnet group in Accelerator Division VI (Light Source Division) of the Accelerator Laboratory from April 2011 to March 2023. His main research subject is advanced light sources such as high-power free-electron lasers (FELs) based on energy-recovery linac (ERL) and next-generation synchrotron radiation sources. He received his Ph. D in Physics from the University of Tokyo in 1987. He first worked as a research associate for the Photon Factory at KEK from 1987 to 1996 and then worked as an associate professor in the Synchrotron Radiation Laboratory of the Institute for Solid State Physics (ISSP) at the University of Tokyo from 1996 to 2011.
