A recently proposed octahedral spherical hohlraum with six laser entrance holes (LEHs) is an attractive concept for upgraded facility aiming at a predictable and reproducible fusion gain simple target design. However, the energies available present, LEH size can be critical issue. Owing to uncertainties in simulation results, should determined on basis of experimental evidence. determination ignition small-scale poses difficulties. In this paper, we propose use prepulse pulse determine...
In inertial confinement approaches to fusion, the asymmetry of target implosion is a major obstacle achieving high gain in laboratory. A recently proposed octahedral spherical hohlraum makes it possible naturally create irradiation without supplementary symmetry control. Before any decision made pursue an ignition-scale laser system based on hohlraum, one needs test concept with existing facilities. Here, we report proof-of-concept experiment for novel geometry cylindrically configured SGIII...
The well-sampled optical light curves of S5 0716+714 in BVRI bands spanning about 20 years were built. variability asymmetry could provide independent constraints on physical models for blazars variability. To perform analyses properties, individual flares decomposed and fitted from the with functions exponential rise decay. In order to investigate whether short term (STV) intraday (IDV) had different mechanisms origin, timescales analyzed, respectively. Results indicate that both STV IDV...
The Be-based materials with many particular properties lead to an important research subject. investigation progresses in the fabrication technologies are introduced here, including main three kinds of materials, such as Be–Cu capsule, $\text{Be}_{2}\text{C}$ ablator and high-purity Be material. Compared pioneer workgroup on differences target were described, a grain refinement technique by active hydrogen reaction for coating was proposed uniquely. coatings first prepared DC reactive...
The Large High Altitude Air Shower Observatory (LHAASO) will be constructed at Mountain Haizi, in Sichuan Province, China (4410m a.s.l.). Water Cherenkov Detector Array (WCDA), one of the major component LHAASO, focus on surveying northern sky for gamma ray sources from 100 GeV to 30 TeV. whole WCDA, owing an area 78,000 m^{2}, is subdividing into 3120 detector cells (5×5 m^{2} each, with a water depth 4m). Every cell has 8 or 9-in PMT residing bottom collect lights produced by charged...
In laser plasmas, the electron distribution function is not Maxwellian but super-Gaussian due to inverse bremsstrahlung heating, and heat transport generally nonlocal because of large Knudsen number. Starting from Fokker–Planck equation, we develop a model based on non-Maxwellian function. our study, follow method in Schurtz et al. [Phys. Plasmas 7, 4238 (2000)] derive differential equation for calculating flux The numerical results show that would reduce heated region. preheat effect...
The electron heat transport plays an important role in laser driven inertial confinement fusion. For the plasmas created by intense laser, traditional Spitzer–Härm theory cannot accurately describe process mainly due to two physical effects. First, distribution function would significantly differ from Maxwellian because of inverse bremsstrahlung heating. Second, long mean free paths carrying electrons relative temperature scale length indicate that flux has nonlocal feature. In 2020, we have...
Escape of α-particles from a burning or an ignited deuterium-tritium (DT) hot-spot with temperature up to more than tens kilo-electron-volts is very important in inertial confinement fusion, which can significantly influence not only the dynamics but also energy gain. In this paper, we study α-particle escape DT by considering modifications, including stopping both ions and electrons their Maxwellian average weights, relativity effect on electron distribution, modified Coulomb logarithm DT-α...
In modeling the charged alpha particle transport in hot-spot plasmas of inertial confinement fusion, energy-losing rate is a major concern Monte Carlo simulations radiative-hydrodynamic code. However, traditionally used energy stopping-power only describes averaged incident particles, whereas variance exchange with background particles generally ignored. this paper, collisions studied by both analytical derivation and simulations. An expression divergence given for first time, which can be...
In 2021, the fusion yield of 1.35 MJ was produced at NIF by using indirect drive inertial confinement (ICF), indicating that ICF has reached ignition. However, driving radiation flux on capsule inside Hohlraums is still a puzzle in studies. The energy deficit neither well understood nor solved. this paper, we proposed scheme to determine combination shock wave technique and reemitted measurement. scheme, witness sample placed Hohlraum center as surrogate capsule. velocity measured streaked...
