PLASMA JET EMITTER: MECHANISM OF ION BEAM FORMATION WITH LOW EMITTANCE

摘要

Plasma emitter, which has been developed inrnNovosibirsk for diagnostics in Tokamak type plasma, is investigated conceptually in order to apply the source to a high intensity particle generation with long range focusing. The effect of thermodynamic cooling in the expansion of charged particles is examined as well as the effect of the restriction of radius in phase diagram of expanded collisionless plasma. The magnetic field is calculated for designing the geometric parameter of the plasma jet emitter.
