Description
Pohang Light Source-II (PLS-II) is a third-generation synchrotron light source operated by the Pohang Accelerator Laboratory (PAL) since 2012. This study was conducted as a preliminary investigation for upgrading the linac to improve the beam operation efficiency of PLS-II. In this system, beam bunching is initially performed using a pre-buncher operating at the same frequency. To achieve more efficient beam bunching, we considered sub-harmonic buncher (SHB). Two cavities with frequencies of 1 GHz and 500 MHz were designed and beam dynamics simulations were performed, taking into account the available installation space. By comparing the bunch length of beam and other beam parameters for each cavity, we confirmed that the SHB could improve injection efficiency compared to the pre-buncher.
