To minimize expenses and time spent on modifying the hardware environment, simulation is commonly employed to acquire the performance parameters of the detector prior to determining its geometrical parameters. This allows for guidance in the construction of the detector. Energy spectrum measurement is a fundamental aspect of detector operation. By measuring the energies of incident particles, we can gain insight into the sort of particles involved and the specific nuclear processes that occur, as the energy released during nuclear reactions and decays are distinct and characteristic. Additionally, energy spectroscopy is used to acquire important information regarding essential material and device properties, such as CCE, FWHM, and μ-τ (carrier mobility lifetime product).
