Optimization of hole-boring radiation pressure acceleration of ion beams for fusion ignition Tập 3 - Trang 28-39 - 2018
S.M. Weng, Z.M. Sheng, M. Murakami, M. Chen, M. Liu, H.C. Wang, T. Yuan, J. Zhang
In contrast to ion beams produced by conventional accelerators, ion beams
accelerated by ultrashort intense laser pulses have advantages of ultrashort
bunch duration and ultrahigh density, which are achieved in compact size.
However, it is still challenging to simultaneously enhance their quality and
yield for practical applications such as fast ion ignition of inertial
confinement fusion. Compare... hiện toàn bộ
Recent progress in ICF target fabrication at RCLF Tập 3 - Trang 135-144 - 2018
Kai Du, Meifang Liu, Tao Wang, Xiaoshan He, Zongwei Wang, Juan Zhang
Target is one of the essential parts in inertial confinement fusion (ICF)
experiments. To ensure the symmetry and hydrodynamic stability in the implosion,
there are stringent specifications for the target. Driven by the need to
fabricate the target required by ICF experiments, a series of target fabrication
techniques, including capsule fabrication techniques and the techniques of
target character... hiện toàn bộ
Theoretical simulation of high-voltage discharge with runaway electrons in sulfur hexafluoride at atmospheric pressure Tập 1 - Trang 264-268 - 2016
Andrey V. Kozyrev, Vasily Yu. Kozhevnikov, Natalia S. Semeniuk
The results of theoretical simulation of runaway electron generation in
high-pressure pulsed gas discharge with inhomogeneous electric field are
presented. Hydrodynamic and kinetic approaches are used simultaneously to
describe the dynamics of different components of low-temperature discharge
plasma. Breakdown of coaxial diode occurs in the form of a dense plasma region
expanding from the cathode.... hiện toàn bộ

Recently we are witnessing the boom of high-pressure science and technology from
a small niche field to becoming a major dimension in physical sciences. One of
the most important technological advances is the integration of synchrotron
nanotechnology with the minute samples at ultrahigh pressures. Applications of
high pressure have greatly enhanced our understanding of the electronic, phonon,

Investigation of spherical and concentric mechanism of compound droplets Tập 1 - Trang 213-223 - 2016
Meifang Liu, Lin Su, Jie Li, Sufen Chen, Yiyang Liu, Jing Li, Bo Li, Yongping Chen, Zhanwen Zhang
Polymer shells with high sphericity and uniform wall thickness are always needed
in the inertial confined fusion (ICF) experiments. Driven by the need to control
the shape of water-in-oil (W1/O) compound droplets, the effects of the density
matching level, the interfacial tension and the rotation speed of the continuing
fluid field on the sphericity and wall thickness uniformity of the resulting

Review of quantum collision dynamics in Debye plasmas Tập 1 - Trang 237-248 - 2016
R.K. Janev, Songbin Zhang, Jianguo Wang
Hot, dense plasmas exhibit screened Coulomb interactions, resulting from the
collective effects of correlated many-particle interactions. In the lowest
particle correlation order (pair-wise correlations), the interaction between
charged plasma particles reduces to the Debye–Hückel (Yukawa-type) potential,
characterized by the Debye screening length. Due to the importance of Coulomb
interaction scr... hiện toàn bộ
First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole Tập 1 - Trang 2-7 - 2016

The octahedral spherical hohlraums have natural superiority in maintaining high
radiation symmetry during the entire capsule implosion process in indirect drive
inertial confinement fusion. While, in contrast to the cylindrical hohlraums,
the narrow space between the laser beams and the spherical hohlraum wall is
usually commented. In this Letter, we address this crucial issue and report our
