The properties of hot, dense plasmas produced by laser irradiation of an isolated solid particle suspended in vacuum have been investigated and studies made of the use of such plasmas confined within a mirror magnetic field as the target for an energetic neutral beam to form a steady state fusion plasma. Theoretical analysis of the mechanism of plasma production and the role of local ionization and recombination on the properties of the afterglow plasma were performed and found to be in excellent agreement with experimental measurements of the time history of the plasma properties obtained from charge collectors, mass spectrometer and line radiation diagnostics. Survey calculations were used to develop empirical formulas relating the irradiating laser characteristics to the properties of the resulting plasma over a wide range of initial particle size and laser heating conditions.
