Comparison of performances of signal digitizers for radiation detectors and transmission measurements

In this report, in the first chapter, it is explained how digitizers will replace analog acquisition as they are more efficient and economic devices despite their complexity. Indeed, this study was made for a better understanding of their working principle and specifications. Then, along the second chapter, the experimental setup with many configurations grouped in 3 main campaigns have been defined to determine ; time and energy resolutions such as the PSD capabilities of the different digitizers. Some detectors and radioactive sources are more adapted for each campaign, and their corresponding ABCD configurations have been detailed. The third chapter of this report was centered on the data treatment ; procedures have to be followed for a great ABCD configuration and optimization of the data size. The optimization process of the waveform analysis allowed by the replay option offered by ABCD and driven by python scripts have also been detailed. No final result have been given because of lake of time and experimental campaign still ongoing. And final, the fourth chapter have detail two other experiment, one that has allowed to prepare the python script for the main experiment. The second one was about transmission measurements on the NATPb at GELINA that have revealed great results.
