Title: Improved generation of ion fluxes by a long laser pulse using laser-induced cavity pressure acceleration

Generation of ion fluxes in the laser-induced cavity pressure acceleration (LICPA) scheme is investigated by the time-of-flight method and compared with the one in the conventional laser-planar target interaction scheme. It is shown that the ion current density and intensity of the ion flux produced in the LICPA scheme from CD{sub 2} foil target irradiated by a 0.3-ns laser pulse of intensity ∼10{sup 14}–10{sup 15} W/cm{sup 2} are by an order of magnitude higher and the mean and maximum ion energies by a factor 4–5 higher than those for the conventional scheme.
