    Laser-target experiments at PALS for deuterium plasma beam fusion

  • Original language description

    The Prague Asterix Laser System (PALS) is a terawatt iodine laser (1.2 kJ, 350 ps, 1315 nm), designed to deliver irradiance on target of about 3 × 1016 W/cm2. The PALS laser together with a Ti:sapphire laser (1 J, 50 fs, 800 nm) is used for experiments allowing femtosecond probing of laser-produced plasma. We present an experimental study of emission of hot electrons, fast ions and fusion neutrons generated through the 2H(d,n)3He fusion reaction of deuterons. During the laser–plasma interaction and plasma expansion, a multi-population of electrons appears. Non-isotropic emission of fast as well as thermal electrons is typical for the interaction of nanosecond laser radiation with plasma. The production of relativistic electrons makes it possible to accelerate protons to MeV energy and generate fusion neutrons via fusion reactions. The DD-neutron yield is compared to yields obtained from other experiments.
