The screen system described in this article is designed to meet the needs of a synchrotron radiation beamline at Taiwan Photon Source (TPS). In the design of the mechanical structure, we combined a square chamber and a coaxial cooling tube for spatial efficiency. The coaxial cooling tube with a fluorescent plate is controlled with a cylinder or motor. The fluorescent materials, diamond and YAG:Ce, are excited with synchrotron radiation to produce a fluorescent image captured with the CCD. With image processing, the beam profile and position are confirmed. This screen monitor is widely used at the TPS beamlines.
