ION GENERATION FROM AL-LASER-PRODUCED PLASMA

Particle diagnostics of Al-laser-produced plasma based on ion collecto rs identified three groups of emitted ions. Their velocity distributio ns were analyzed to obtain the mean ion energy, energy and charge carr ied by ions, including the angular distributions of these quantities. The electron temperature evaluated from these measurements was compare d with X-ray results. A satisfactory agreement between the two sets of data was found. In both the cases the electron temperature grows only very slowly with the incident laser power. Origin of different ion gr oups is discussed. Iodine photodissociation laser system PERUN was use d as a driver.
