Master thesis defense by Bar Davids

Fabrication of isotopically pure, precisely doped components is essential to reducing noise in solid-state qubit systems. This thesis establishes a computational framework for optimizing ion deflection systems in UHV environments by combining COMSOL electrostatic simulations with Python-based beam modeling. Applied to silicon ions and carbon dimers, more than 2,600 parameter variations and one million simulated particles identified designs achieving up to 35% collection efficiency and sub-millimeter spatial resolution. The study highlights boundary effects, design methodology, and high-velocity beam dynamics as key to improved focusing, purification, and scalability in quantum hardware fabrication.
