Multi-Turn Electron-Ion Injection Study for Neutralized High-Density Beam Sustaining in a Closed Configuration

The problem of creating a high-density, high-current neutralized beam in a closed configuration via a continuous particle injection and accumulation has been considered in relation to the research on a colliding beam fusion process.

The last results, oriented to the development of a basic neutralized beam experiment, are discussed.

The theory of resistive wall injection of a charged particle ring is reviewed and the application to the simultaneous injection of electron and ion rings is introduced.
