With the development of ultra-intense laser technology, MeV ions can be obtained from laser-foil interactions in the laboratory. These energetic ion beams can be applied in fast ignition for inertial confinement fusion, medical therapy, and proton imaging. However, these ions are mainly accelerated in the laser propagation direction. Ion acceleration in an azimuthal orientation was scarcely stu...

LLE Review, Volume 135 173 Introduction Fast-electron generation in laser–plasma interactions has long been of interest for a variety of reasons, such as avoiding preheat during compression in inertial confinement fusion (ICF), heating the compressed core of an ICF target for fast ignition,1 generating a shock in an ICF target for shock ignition,2 and as a means to produce energetic secondary p...

Our experimental group develops methods to detect high-energy electrons produced by laserplasma instabilities. These electrons, which range up to hundreds of keV , prove a major challenge for inertial confinement fusion (such as at NIF). They can preheat fuel, resulting in more energy being required to compress fuel to the point of ignition. We concentrated a laser (to an intensity of 10 ∼ 10W/...

The dispersion of ion-acoustic fluctuations has been measured using a novel technique that employs multiple color Thomson-scattering diagnostics to measure the frequency spectrum for two separate thermal ion-acoustic fluctuations with significantly different wave vectors. The plasma fluctuations are shown to become dispersive with increasing electron temperature. We demonstrate that this techni...

Calculations were performed to quantify the damage parameters in the leading candidate structural and plasma facing materials when used in magnetic and inertial confinement fusion systems and when irradiated in fission reactors. The structural materials considered are ferritic steel, austenitic steel, vanadium alloy and SiC/SiC composite. Plasma facing materials included beryllium, tungsten, an...

Abstract Tokamak and inertial confinement fusion(ICF) are two kinds of devices to achieve fusion. Magnetic gravitational fields the drivers used in tokamak ICF, respectively. In other fusion like MIF, both them used. this work, different from these mentioned above, a new promising method confine plasma is proposed. Spacial distribution energy high-speed changing magnetic field simulated. This e...

Stimulated Raman and Brillouin scattering of laser radiation in a plasma corona are outstanding issues for the inertial confinement fusion. may produce absorption significant fraction energy near quarter critical density associated with cavitation generation hot electrons. By contrast, stimulated operates lower prevents light access to region. In present paper, we report results analysis compet...

Measurement of magnetic field is one of critical parameters for Fast ignition in inertial confinement fusion research. Not only that the field inside plasma affects the transport of fast electrons generated in intense laser pulse-plasma interactions, but also that measurement of the field is one of good tools for investigation the current of fast electrons, resulting in estimation of conversion...
