<RESEARCH REPORT>Edge Effect and Its Measures of the Light Ion Beam Propagation in ICF

概要
- 論文の詳細を見る
The effects due to the electrostatic field caused at the two edges are discussed. This intense electric field (about 10^5V/m∿10^6V/m) is caused by the nonneutrality of the ion- beam-charge, and it would destroy the beam equilibrium, thus the beam propagation will be in difficulty. It is proposed to inject electron beam at the same time the injection of ion beam to neutralize the ion-beam-charge. In this case, the plasma channel may be required to suppress the ion beam expansion by thermal diffusion. The channel current is order of 10^5A. If it is difficult to obtain this channel current technically, the method to remain the self-current of the ion beam is proposed. The radial expansion would be suppressed and pinched by self-azimuthal-magnetic-field. The axial expansion would be suppressed about 1/4 of the case of channel propagation.
