即将建立的探测器设施旨在开发新的最先进的粒子探测器，并为研究生提供使用核辐射探测器模拟和数字信号处理的实践培训。该项目有两个方面，旨在开发：1）与iThemba实验室新的GAMKA阵列耦合的辅助探测器。我们小组特别感兴趣的是确定核形状，这取决于磁子的超精细分裂; 2）使用更便宜的技术进行癌症成像的PET扫描仪。使用XIA数字电子公司的PIXIE-16模块评估了NaI（Tl）无机闪烁体探测器的性能。利用60 Co和137 Cs源的γ能谱数据计算了探测器的分辨力，并优化了数字化参数。本研究的重点是改进和优化的慢，快过滤器的参数NaI（Tl）探测器，最终可以用于数据采集的列表模式。
The upcoming detector facility aims at developing new state-of-the-art particle detectors as well as providing hands-on training to postgraduate students using both analog and digital signal processing from nuclear radiation detectors. The project is two-fold and aims at developing: 1) ancillary detectors to be coupled with the new GAMKA array at iThemba LABS. Of particular interest to our group is the determination of nuclear shapes, which depend on the hyperfine splitting of magnetic substates; 2) PET scanners for cancer imaging using a cheaper technology. Performance of NaI(Tl) inorganic scintillator detectors has been evaluated using PIXIE-16 modules from XIA digital electronics. Gamma-ray energy spectra were acquired from60Co and137Cs radioactive sources to calculate the detector resolution as well as to optimize the digital parameters. The present study focuses on improving and optimizing the slow and fast filter parameters for NaI(Tl) detectors which can eventually be used in the list mode of data aquisition.
