Light Source Developments at UVSOR BL1U

Abstract

UVSOR, a low energy synchrotron light source, has been operational for about 40 years. It has been providing high brightness VUV radiation to users but also providing a research environment for light source developments. BL1U is a dedicated beamline for developments and applications of novel light source technologies. The beamline is equipped with two variable-polarization undulators with a phase-shifter magnet and with a femto-second laser system which is synchronized with the RF acceleration. We have been studying oscillator-type free electron laser, coherent harmonic generation, coherent synchrotron radiation, inverse Compton scattering and spatiotemporal-structured light. We have also been exploring their applications, in collaboration with researchers from universities and research institutes.
