Abstract
En 中文
This study presents a comprehensive application and validation of a multi-software coupling workflow for the research and development of gaseous detector systems. The integrated workflow includes particle interaction (Geant4/Garfield++), electrostatic field computation (COMSOL), electronic response (LTspice), and digital signal processing (ROOT). Applied to a Frisch-grid ionization chamber (FGIC) developed for the High-Intensity heavy-ion Accelerator Facility (HIAF), the integrated system simulates the entire response chain, including geometric structure modeling, particle source definition and interactions, electric field distribution calculations, electron-ion transport, electronic circuit response, and digital shaping algorithms. The key advantage of this systematically integrated approach lies in its ability to perform waveform-level simulation and validation. As demonstrated by the FGIC case study, the simulated waveforms show a correlation coefficient of 0.9 with measurements, and the energy spectra exhibit a peak position deviation of < 0.5%, confirming the high-fidelity physical simulation of gaseous detectors. This methodology provides a tool for optimizing the design of the FGIC and interpreting its experimental data, with general applicability to other gaseous detector development efforts.
