Description

As the power density of photon beams increases in low emittance storage rings, robust and non-destructive diagnostic tools are required to replace conventional invasive monitors. Although existing Ionization Profile Monitors have demonstrated sufficient resolution for position measurement, the spatial resolution required for accurate profile reconstruction has rarely been analyzed in relation to electromagnetic field design. This presentation shows the development of a White Beam Profile Monitor capable of precise photon beam profile measurement. We utilized an electrode geometry to maximize the readout area. A key feature of our approach is the quantitative analysis of the Point Spread Function, achieved by numerically calculating the motion of ions generated during ionization. Verification tests performed at the PLS-II beamline confirmed that the measured profiles are consistent with simulation results, thereby validating our resolution analysis and demonstrating the reliable performance of the WBPM.
