In order to conduct research on γ-radiation, the TANGRA project [1] utilizes two semiconductor detectors made of high-purity germanium, as germanium possesses a small band gap and the lowest energy of formation of an electron-hole pair in comparison to other semiconductors. In TANGRA experiments, customized digitizers are applied, with the resulting signals fed into the Romana software developed as part of the project. The software is used for the recording and processing of signals from the detectors. The Romana software employs a specialized approach to obtain spectrometric measurements. However, the energy resolution (FWHM) is observed to degrade significantly as the detector load increases. One potential solution to this resolution loss is an increase in the processing area of the signal. Unfortunately, this approach may result in a situation where the processing system is unable to maintain the required rate of data processing, leading to the loss of the data. Therefore, alternative methods of digital signal processing were developed and the optimal parameters were identified with respect to the best energy resolution and high detector load. The following report presents the latest studies on the optimization of parameters for a set of methods used for processing digitized signals from semiconductor detectors made of high-purity germanium.
