Norio Nakamura is a professor emeritus and researcher in accelerator-based light sources at High Energy Accelerator Research Organization (KEK). 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 worked for the Photon Factory at KEK 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. From April 2011 to March 2023, he was a professor and leader of the beam dynamics and magnet group in Accelerator Division VI (Light Source Division) of the Accelerator Laboratory at KEK.
