AbstractOne-dimensional particle-in-cell and Monte-Carlo (FLUKA) simulation methods were used together, in order to investigate the production of positrons in lead targets, illuminated by a short-pulse high-intensity laser. The study is focused on lead targets of 1 mm thickness and more and pulses of intensity in the range 1019–1022 W/cm2. The calculations provided an estimate of an absolute number of positrons and the ratio of electrons and positrons emerging from the target. The thickness of the target is scaled in order to find an optimal thickness that could provide a neutral electron-positron beam.

AbstractA scheme capable of enhancing the energy of monoenergetic protons in high intensity laser-plasma interactions is proposed and demonstrated by two dimensional particle-in-cell simulations. The focusing of laser light pulse and the guiding of surface currentviathe highZmaterial cone-shaped substrate increase the temperature of hot electrons, which are responsible for the electrostatic field accelerating protons. Moreover, the sub-micron proton layer coated on the cone-shaped substrate makes the total proton beam experience the same accelerating field, thus the monochromaticity is maintained. Compared to the normal film double layer target, the energy of monoenergetic proton beams can be improved about three times.

Experience has shown that at sufficiently high intensity, laser–target interaction is dominated by long mean-free-path electrons generated by resonance absorption. Experimental observations relating to the generation and target coupling of these hot electrons are reviewed with particular emphasis on results obtained in CO2 laser interaction experiments at the National Research Council of Canada. Possible applications of laser-generated hot electrons as a direct driver for inertial-confinement fusion are discussed.
