High beta capture and mirror confinement of laser produced plasmas
Abstract
A dense, mirror confined, target plasma is produced by high power laser irradiation of a solid lithium hydride particle, electrically suspended in a vacuum at the center of an established minimum-B magnetic field. Following expansion in and capture by the magnetic field, this target plasma is irradiated by an energetic neutral hydrogen beam. Charge exchange collisions with energetic beam particles serve to heat the confined plasma while ionization of the neutral beam atoms and trapping in the mirror magnetic field add particles to the confined target plasmas and initial studies of energetic neutral beam injection into confined target plasmas, conducted are presented. Improvements in the laser plasma production facility, the energetic neutral beam line, and the heavy ion probe diagnostic are reported.
