I would like to thank Helen Edwards who gave me the opportunity to do this internship at Fermilab in the laboratory of A0, and who regularly guided me and advised me with patience, making this project challenging, and thus enjoyable. I would also like to thank Philippe Piot, who spent a lot of time discussing with me, eitheir to help me in the implementation of the algorithm, or to help me in the interpretation of simulation results by explaining me the theory behind it. He replied with attention to each of my questions, and thank to this, it was a real pleasure to study particle physics. I wish to thank Bruce Popper and Steve Wesseln, who provided me amazingly quickly with the coordinates and drawing of A0 and NML. Among A0 team, James Santucci, and Amber, helped me several times at work, but I am mainly grateful for their moral support that counted a lot. Again, from A0 team, thank you to Wayne for the different coffee time, and to Elvin Harms for welcoming me in the team, and helping me to settle during the first weeks. I would like to thank all the personnel from Fermilab I met. If it was for scientific or administrative purpose, or if it was in spare time, they all welcomed me with attention. They all participate in making this project a rich adventure. Eventually, my last words would be for my brother, Julien, who has been supporting me all this time, cheering me up, and who did a lot for me to enjoy my stay in the US. Merci Julien.
