Control of Electron Beam Using Strong Magnetic Field for Efficient Core Heating in Fast Ignition
T. Johzaki, T. Taguchi, Y. Sentoku +6
For enhancing the core heating efficiency in electron-driven fast ignition, we proposed the fast electron beam guiding using externally applied longitudinal magnetic fields. Based…
Plasma-wall interaction in laser inertial fusion reactors: novel proposals for radiation tests of first wall materials
J. Alvarez Ruiz, A. Rivera, K. Mima +8
Dry-wall laser inertial fusion (LIF) chambers will have to withstand strong bursts of fast charged particles which will deposit tens of kJ m and implant more than 10…
Laser-ion acceleration via anomalous electron heating
A. Yogo, K. Mima, N. Iwata +23
Using a kilojoule class laser, we demonstrate for the first time that high-contrast picosecond pulses are advantageous for ion acceleration. We show that a laser pulse with optimum…
Integrated simulation of magnetic-field-assist fast ignition laser fusion
T. Johzaki, H. Nagatomo, A. Sunahara +13
To enhance the core heating efficiency in fast ignition laser fusion, the concept of relativistic electron beam guiding by external magnetic fields was evaluated by integrated simu…
Generation of High Quality Laser Accelerated Ion Beams
T. Zh. Esirkepov, S. V. Bulanov, K. Nishihara +9
In order to achieve a high quality, i. e. monoergetic, intense ion beam, we propose the use of a double layer target. The first layer, at the target front, consists of high-Z atoms…
Laser-Shock Compression and Hugoniot Measurements of Liquid Hydrogen to 55 GPa
T. Sano, N. Ozaki, T. Sakaiya +19
The principal Hugoniot for liquid hydrogen was obtained up to 55 GPa under laser-driven shock loading. Pressure and density of compressed hydrogen were determined by impedance-matc…
Collimated electron jets by intense laser beam-plasma surface interaction under oblique incidence
H. Ruhl, Y. Sentoku, K. Mima +2
Oblique incidence of a -polarized laser beam on a fully ionized plasma with a low density plasma corona is investigated numerically by Particle-In-Cell and Vlasov simulations in…
