Boron-Proton Nuclear-Fusion Enhancement Induced in Boron-Doped Silicon Targets by Low-Contrast Pulsed Laser
A. Picciotto,Daniele Margarone,Andriy Velyhan,Pierluigi Bellutti,Josef Krasa,A. Szydlowsky,Giuseppe Bertuccio,Yongbiao Shi,A. Mangione,J. Prokupek,A. Malinowska,E. Krousky,Jiri Ullschmied,Leos Laska,Milan Kucharik,G. Korn +15 more
TL;DR: In this article, it was shown that high fluxes of alpha particles can be obtained using only moderate-power lasers, which is the same as the one used in this paper.
Journal ArticleDOI
Fusion energy using avalanche increased boron reactions for block-ignition by ultrahigh power picosecond laser pulses

TL;DR: In this article, it was shown that secondary avalanche reactions are happening and confirming the results of high-gain, neutron-free, clean, safe, low-cost, and long-term available energy.
Journal ArticleDOI
Generation of high pressure shocks relevant to the shock-ignition intensity regime

TL;DR: In this paper, an experiment was performed using the PALS laser to study laser-target coupling and laser-plasma interaction in an intensity regime ≤1016W/cm2, relevant for the "shock ignition" approach to Inertial Confinement Fusion.
Journal ArticleDOI
Measurement of the target current by inductive probe during laser interaction on terawatt laser system PALS
Jakub Cikhardt,Josef Krasa,M. De Marco,Miroslav Pfeifer,Andriy Velyhan,E. Krouský,B. Cikhardtova,Daniel Klir,K. Řezáč,Jiri Ullschmied,Jiri Skala,P. Kubes,J. Kravarik +12 more
TL;DR: A return-current dependence of the electromagnetic pulse produced by the laser-target interaction is presented and shows that the target current is proportional to the deposited laser energy and is strongly affected by the shot-to-shot fluctuations.
Journal ArticleDOI
Highly efficient accelerator of dense matter using laser-induced cavity pressure acceleration
J. Badziak,S. Jabłoński,T. Pisarczyk,P. Rączka,E. Krousky,Richard Liska,Milan Kucharik,Tomasz Chodukowski,Zofia Kalinowska,Piotr Parys,Marcin Rosinski,S. Borodziuk,Jiri Ullschmied +12 more
TL;DR: In this paper, the authors proposed and demonstrated a highly efficient scheme of acceleration of dense matter in which a projectile placed in a cavity is irradiated by a laser beam introduced into the cavity through a hole and then accelerated in a guiding channel by the pressure of a hot plasma produced in the cavity by the laser beam or by the photon pressure of the ultra-intense laser radiation trapped inside the cavity.
