abstract = {{The Beam Position Monitors (BPMs) for the new Thailand synchrotron light source, Siam Photon Source II (SPS-II), has been designed utilizing as the essential tool for diagnosing the position of the beam in the storage ring. Its design with four-button type BPM has been optimized to obtain the high precision of position data in normal closed orbit and feedback mode as well as turn by turn information. We calculate feedthroughs capacitance, sensitivities, induced power on a 50 Ω load, and intrinsic resolution by using Matlab GUI developed by ALBA, to find the appropriate position, thickness, and gap of the BPM button. Extensive simulation with the electromagnetic simulation tool CST Particle Studio was also performed to investigate the dependence of the induced BPM signal, wakefield, Time Domain Reflectometry (TDR), and power loss on different BPM geometry.}},
