Publication Abstract: The present thesis discusses the main aspects and results of the ongoing SBS-GEM development, production and test, according to the following structure: - In chapter 1 the theoretical and experimental importance of nucleon electromagnetic form factors is described. Furthermore, the discrepancy of ep scattering data obtained about the FFs ratio between the Rosenbluth separation method and the polarization transfer method is highlighted and, therefore, the Super Bigbite Program at JLab is introduced. - In chapter 2 the experimental apparatus of the SBS project is described, focusing on the main components of the spectrometers involved; the Super Bigbite Spectrometer for the hadron arm and the BigBite spectrometer for the electron arm. - Chapter 3 describes the SBS/BB front tracker and the motivation on the GEM technology choice. In addition, the main features and advantages of the technology used are also described. - Chapter 4 describes the commissioning of the GEM trackers at JLab. The whole iter of the GEM modules is presented, from the assembly in clean-room to the characterization tests with cosmic rays performed at JLab. - In chapter 5 a new method of analyzing the signals extracted from the strips of GEM modules is introduced. This study goal is the real-time suppression of noisy data by mean of innovative A.I. techniques.
