Ionization
How heavy atoms are turned into beams of charged particles.
Ionization is the process of removing electrons from atoms to create a charged particle. In heavy ion sources, different techniques are used depending on the desired charge state and beam current.
Ionization overview
Different source types offer various trade-offs in efficiency, charge tuning, and complexity. Explore common methods and where they are used.
Plasma fundamentals
A plasma is an ionized gas with free electrons and ions. The conditions inside an ion source are engineered to sustain the plasma while extracting the desired ions.
Sputter ionization
Sputter sources are widely used for negative-ion production using solid targets and cesium-assisted surface processes. They are especially common in injector front-end systems.
