    ABSTRACT: A diagnostic beamline has been operated in the PLS storage ring for the diagnostics of electron- and photon-beam properties. It consists of two optical imaging systems: a visible light imaging system and a soft X-ray imaging system. We measure transverse and longitudinal beam structure with a streak camera to study short-time beam dynamics from the visible light image. Accurate transverse beam size is measured with soft X-ray image to minimize diffraction error. In this paper, results of the beam studies and the measurement of beam parameters are summarized and discussed

    ABSTRACT: A diagnostic beamline has been operated in the Pohang Light Source (PLS) storage ring for the diagnostics of electron and photon beam properties. It consists of two 1:1 imaging systems: a visible-light imaging system and a soft X-ray imaging system. We have measured the transverse and the longitudinal structures of beams by using a streak camera to obtain a visible image. Accurate transverse beam sizes have been measured to be 186 μm horizontally and 43.1 μm vertically by using soft X-ray images with minimum diffraction errors. The corresponding emittances are 11.7 nm-rad horizontally and 0.59 nm-rad vertically. By comparing the measured data with the design values, we confirmed that the PLS storage ring has reached its design performance within an error of 3.3 % in the transverse direction.
