The Ion Beam Induced Charge (IBIC) analysis method is a powerful technique for investigating the charge collection efficiency (CCE) in semiconductor materials. It is also widely employed to study the effects of ionizing radiation on the performance of electronic devices and to evaluate the response of charged-particle detectors under irradiation conditions. In this work, an 241Am alpha source and an ion-implanted silicon charged-particle detector were used in a vacuum chamber. By varying the detector bias voltage—thereby altering the depletion layer depth—and measuring the alpha spectra, the CCE was determined. In addition, numerical simulations were performed to estimate the CCE. The simulation results showed good agreement with the experimental data and accurately reproduced the dependence of CCE on bias voltage. By providing both experimental and simulation-based analyses of charged-particle detector performance using the IBIC method, this study contributes to a deeper understanding of detector behavior under irradiation and supports various scientific, and technological applications.
