Intense-heavy-ion-beam transport through an insulator beam collimator

We study an intense-heavy-ion-beam transport through an insulator beam guide by a particle simulation in heavy ion inertial confinement fusion. we have proposed a new system for an electron and proton beam transport using an insulator beam guide. We apply this system to a Cs⁺ beam transport and a Pb⁺ beam transport. An intense heavy ion beam creates a local electric field on the insulator inner surface, and generates a plasma on the surface of the insulator guide. Electrons are extracted from the plasma, and the beam charge is effectively neutralized by the electrons. The electron extraction is self-regulated by the net space charge of the beam. Consequently, an intense heavy ion beam can be efficiently transported by the proposed simple system.
