BL1U Light Source Development Station
Description
BL1U is dedicated for developments and applications of novel light sources. This beamline is equipped with a dedicated tandem undulator for variable polarization with a buncher section, which can be used for free electron laser in the range from visible to deep UV, VUV coherent harmonic generation (CHG), and generation of spatiotemporal structured light such as an optical vortex beam, a vector beam and double-pulse wave packets. It is also equipped with a femto-second laser system synchronized with the accelerator, which is used for the generation of CHG, laser Compton scattered gamma-rays, and coherent THz radiation. Nowadays, material analysis by positron annihilation spectroscopy using laser Compton scattered gamma rays is actively used.
