Description

The beam scraper system for the Siam Photon Source II (SPS-II) storage ring is under development to provide reliable beam halo control and protection of insertion devices. Following the completion of the horizontal scraper, current efforts are dedicated to the vertical scraper, where the large blade width and restricted vertical aperture introduce significant RF and impedance challenges. Electromagnetic simulation and geometry optimization were performed to evaluate wakefield effects and impedances. The final configuration and detailed results will be presented.
