Description
This work presents the development of a Python-based application program for resistive-wall (RW) impedance and instability analysis for the Taiwan Photon Source (TPS), with general applicability to both the storage ring (SR) and booster ring (BR). The program is intended to provide a practical and extensible tool for evaluating the impact of vacuum-chamber material, geometry, and segmented beam-pipe structure on transverse RW impedance, coherent tune shift, instability growth rate, and growth time. The code integrates analytical RW impedance models with a flexible segmented-machine description, allowing users to define different chamber sections with independent cross section, dimensions, conductivity, and magnetic permeability. A graphical user interface (GUI) is implemented to support convenient parameter input, rapid model updates, and automatic generation of output plots for engineering studies and machine-physics evaluation. The program is designed as a general analysis platform for broader TPS applications, including storage-ring impedance assessment, chamber optimization, and instability-sensitivity scans. This development establishes a reusable computational framework for impedance-informed accelerator design, operation studies, and future feedback or mitigation planning at TPS.
