R&D for gas recovery systems and study of eco-friendly gas mixtures for new gas detectors for the Experiments at the CERN Large Hadron Collider

The doctoral thesis titled "R&D for Gas Recovery Systems and Study of Eco-Friendly Gas Mixtures for New Gas Detectors for the Experiments at the CERN Large Hadron Collider" focuses on developing and optimizing industrial-scale recovery systems for high GWP fluorinated gases. It also studies eco-friendly gas mixtures for particle detectors used in experiments at the CERN Large Hadron Collider (LHC). The thesis emphasizes using fluorinated gases responsible for high greenhouse gas emissions and strategies to reduce their environmental impact, primarily through gas recovery and reuse. Various methods of physical separation including selective membranes and distillation processes are utilized for the recovery of gases such as CF₄, C₂H₂F₄, and C₄F₁₀, which are used in the CMS and LHCb experiments. Additionally, it analyses the importance of developing alternative gas mixtures with low environmental impact and presents results of analyses such as ISE, UV-Vis, and VUV aimed at characterizing the gases currently used in detection and potential more eco-friendly alternatives from a physicochemical perspective.
