BL38B2

◆Outline of beamline

Diagnosis Beamline (BL38B2) has a bending magnet light source, and wide band spectral availability including visible/UV light, and soft and hard X-rays has been achieved. The visible synchrotron light is used for diagnostics of longitudinal properties of the source electron beam, such as bunch length and bunch purity. Bunch length is measured by a streak camera, and bunch purity is measured by a bunch purity monitor based on a gated photon counting method. For diagnostics of transverse emittance of the electron beam, the X-ray beam imager (XBI) based on a single Fresnel zone plate (FZP) and an X-ray zooming tube has been developed. Synchrotron radiation experiments on accelerator components such as photon absorbers, and study of production of 10 MeV γ-ray photons by backward Compton scattering of FIR laser photons are also in progress.
