Electrostatic potential field maps of antimatter traps using numerical analysis
According to the Standard Model, all baryonic matter is predicted to have a corresponding antiparticle. From this premise, we currently dont understand why we observe more matter than antimatter, making the study of antimatter a fascinating subject. My research project is with the ALPHA experiment at CERN, which produces antihydrogen. Composed of an antiproton and a positron bind together, antihydrogen is the matter counterpart of hydrogen. Because of its neutrality and correspondence with the hydrogen atom, it is a desirable system for experimental study. My summer project involves numerical simulations of the positron accumulator Penning trap and ALPHA-g atom trap. The former is one of the first stages of the experiment where positrons are prepared, and the latter is a new upgrade of the experiment where antihydrogen is confined in order to perform gravity measurements to test the Standard Model. The goal is to solve for and display the potential wells used for confinement in order to make direct changes of the traps voltage while getting a preview of the field inside the trap.
