In the studies of optical injections in laser or beam-driven wakefield accelerators, there is a frequent demand for using obliquely propagating assistant lasers particle-in-cell simulations. conventional methods, this only possible either two- three-dimensional Cartesian geometries, which have drawbacks lack fidelity actual situation requiring huge amount computational resources. work, we develop new method that uses an expression-defined oblique field to simulate such situations...
Enhanced understanding of turbulent flow structure in bends natural rivers is essential for waterway regulation, navigation safety and environmental ecological wellbeing. However, the consecutive has so far remained poorly understood, especially when it subject to influence tributary inflow. Here, 3D two bends, namely Qigongling (upstream bend) Guanyinzhou (downstream bend), inflow from Dongting Lake, middle Yangtze River, numerically investigated. The RNG k-ϵ turbulence model applied under...
In this study, organically modified montmorillonite (OMMT) was prepared by modifying MMT with a cationic surfactant cetyltrimethylammonium bromide (CTAB). The obtained OMMT of different loading contents (1, 2, 4, 6, and 8 wt %) melt-blended poly(acrylonitrile-co-butadiene-co-styrene) (ABS) to prepare series ABS/OMMT composites, which were laser marked using neodymium-doped yttrium aluminum garnet (Nd:YAG) beam 1064 nm under current processes. X-ray diffraction (XRD), color difference...
In this study, using molybdenum sulfide (MoS2) as laser-sensitive particles and poly(propylene) (PP) the matrix resin, laser-markable PP/MoS2 composite materials with different MoS2 contents ranging from 0.005 to 0.2% were prepared by melt-blending. A comprehensive analysis of laser marking performance composites was carried out controlling content additives, current intensity, scanning speed marking. The color difference test shows that best can be obtained at 0.02 wt %. surface morphology...
In this work, using ferroferric oxide (Fe3O4) and zirconium (ZrO2) as laser-sensitive particles thermoplastic polyurethane (TPU) the matrix resin, a series of TPU/Fe3O4/ZrO2 composites were prepared by melt blending, effect laser marking additive content, composition, parameters on properties was investigated. The mechanism Fe3O4/ZrO2 additives role each component in TPU studied metallographic microscopy, color difference test, scanning electron Raman spectroscopy. Fe3O4 nanoparticles...
Multiwalled carbon nanotubes (MWCNTs) were carboxylated by nitric acid oxidation/plasma pretreatment, and melamine phosphate (MP) was grafted onto the surface of MWCNTs to obtain functionalised MWCNTs-MP. The modified characterised FT-IR, Raman spectroscopy, XRD, 1H-NMR, TEM, SEM TGA. results proved successful preparation acrylonitrile–butadiene–styrene copolymer (ABS) composites prepared melt blending with MWCNTs-MP using TGA, microscale combustion calorimeter, limiting oxygen index (LOI),...
Abstract We report a novel kind of antiresonant fiber for flat‐top beam generation with all‐solid configuration. The core introduces square antiresonance structure low‐high‐low refractive index distribution, achieving homogenization the profile through its light guidance on optical field. Attributed to structure, transmits very low confinement loss and large mode area. And it generates in wavelength range from 1200 nm 2200 nm. This would open up application shaping.
The thorough exploration of the transverse quality represented by divergence angle has been lacking yet in energy spread measurement relativistic electron beam for laser wakefield acceleration (LWFA). In this work, we fill gap numerical simulations based on experimental data, which indicate that a C-shape magnet, magnetic field possesses focusing effect, considering will result an increase full width at half maxima (FWHM) density distribution uniformly isotropic manner, while length-to-width...
A dual-beam platform for all-optical electron-photon scattering, or Thomson/Compton with adjustable collision-angle and parameter tuning ability has been developed, which, in principle, can be used the verification of strong-field quantum electrodynamics effects. Combining this a 200 TW Ti:Sapphire laser system, we demonstrated generation inverse Compton scattering X/gamma-rays tunable energies from tens keV to MeV. The polarization X/gamma radiation was manipulated by controlling laser. In...
Abstract We report a large mode area photonic crystal fiber with top-hat field. The optical has multi-layer square structure air holes and doped layer. A flat top-hat-like intensity profile is provided through the reasonable design of modal characteristics including effective area, dispersion confinement loss are investigated. proposed generation may have potential applications in laser drilling, cleaning, imaging, spectroscopy, so on.
