First observations on wall plasma expansion and x-ray flux in foam hohlraum at 100 kJ laser facility

Lu Zhang, Zhiwei Lin, Longfei Jing, Jianhua Zheng et autres

The first experiments on laser-driven cylindrical gold foam hohlraums have been performed at the 100 kJ SG-III laser facility. Measurements of the expanding plasma emission show that there is less expanding plasma fill in foam hohlraums with a wall density of 0.8 …

Collision frequency measurement from optical reflectivity of laser indirect-driven CH/Al/diamond

Hou Yong, Yang Zhao, Jiyan Zhang, Tao Xu et autres

Abstract A collision frequency measurement from the optical reflectivity of laser indirect-driven CH/Al/diamond on the SG-10kJ laser facility is presented. The optical reflectivity and the Al/diamond interface velocity were measured simultaneously by the velocity interferometer. The aluminum rear surface density was deduced …

Experimental method for warm dense matter ionization distribution based on X-ray fluorescence pectroscopy

Zhi-Yu Zhang, Yang Zhao, Bo Qing, Jiyan Zhang et autres

Warm dense matter (WDM), a state of matter that lies at the frontier between condensed matter and plasma, is one of the main research objects of high energy density physics (HEDP). Comparing with the isolated atom, the electron structure of WDM will …

The effect of the shroud window membrane on the x-ray drive characterization of cryogenic hohlraums

Dong Yang, Zhichao Li, Sanwei Li, Lifei Hou et autres

Both direct and indirect drive concepts of inertial confinement fusion rely on targets with cryogenic thermonuclear fuel shells for ignition. Experiments on the Shenguang-III prototype laser facility using laser-driven gas-filled hohlraums show distinct differences between cryogenic (20 K) and warm hohlraums. Although …

Density effect on electronic structure of warm dense matter based on X-ray fluorescence spectroscopy

Zhiyu Zhang, Yang Zhao, Bo Qing, Jiyan Zhang et autres

Warm dense matter (WDM), a kind of transition state of matter between cold condensed matter and high temperature plasma, is one of the main research objects of high energy density physics (HEDP). Compared with the structure of isolated atom, the electron structure …

Characterization of radiation drive by measuring the localized re-emitted flux from the capsule in inertial confinement fusion experiments

Xufei Xie, Changshu Wu, Jinwen Chen, Shenye Liu et autres

Abstract We present for the first time characterization of the time-dependent radiation drive on the capsule by measuring the localized re-emitted flux at Shenguang-III prototype laser facility. The drive flux was obtained with measured re-emitted flux from the capsule and radiation fluxes …

Understanding effects of radiation from radiative shock on Richtmyer-Meshkov instability

Yongteng Yuan, Shaoyong Tu, Chuansheng Yin, Jiwei Li et autres

Radiative shocks are ubiquitous in stellar environments and are characterized by high temperature plasma emitting a considerable fraction of their energy as radiation. Radiative shocks occur commonly in nature, especially in astronomical systems and inertial confinement fusion. The study of the effects …

Design and performance study of a gas-Cherenkov detector with an off-axis parabolic reflector for inertial confinement fusion experiments

Zifeng Song, Bin Zhu, Yunqing Xiao, Tao Xu et autres

Abstract In this work, the gas-Cherenkov detector with an off-axis parabolic reflector (OprGCD) is designed using the Geant4 Monte Carlo simulation toolkit, which is helpful to improve the collection efficiency of Cherenkov photons. The method to study the performance of OprGCD based …
