Abstract

Gas detectors are fundamental components present in all experiments in high energy physics. Over the past few years, investments have been made in the development of detectors with excellent spatial resolution, high signal rate counting capability and resistance to damage due to radiation. In the ALICE experiment, experiments are conducted in order to study heavy ion collisions. An upgrade was carried out in the ALICE detector system in order to replace the multiline system with microstructured detectors such as the Gas Electron Multiplier (GEM). This project then seeks to use these high-energy detectors in X-ray fluorescence measurements and build a compact low-cost acquisition and analysis system based on Arduinos. Such a system is of great interest in cultural heritage analysis, where semiconductor detectors with a low coverage area and high cost are mostly used.
