Autor: Wenbing Pei, Tieqiang Chang, Tinggui Feng, Yan Xu, Dongxian Lai, Yongkun Ding, Ke Lan, Shuanggui Li, Shaoeng Jiang

Publikováno v: Laser and Particle Beams. 24:495-501

Radiation transfer in low-density foam is influenced by the external radiation field which impacts on the foam when the size of plasma created in laboratory is not large to be opatical thick. The radiation transfers of different photon groups are sen

Inferring the capsule-absorbed radiation energy from experimental hohlraum radiation temperature

Autor: Wenbing Pei, Tieqiang Chang, Yunsheng Li, Guangyu Wang, Jiatian Sheng

Publikováno v: Physics of Plasmas. 11:4286-4289

For indirect laser fusion, the implosion is driven by the fusion capsule-absorbed radiation energy emitted by laser-produced plasma. However, the absorbed energy could hardly be directly measured experimentally and usually would require numerical sim

Recently, hohlraum experiments were performed at the Shenguang-II (SG-II) laser facility [Lin et al., Chin. J. Lasers B10, Suppl. IV6 (2001)]. The measured maximum radiation temperature was 170 eV for the standard hohlraum and 150 eV for a 1.5-scaled

Relativistic electron heating in laser-produced plasmas

Autor: Zongwu Yue, Wenwei Chang, Lihua Cao, Tieqiang Chang

Publikováno v: Journal of Plasma Physics. 65:353-363

Two-dimensional multi-timescale fully electromagnetic relativistic particle simulation is used to investigate relativistic electron heating in laser-produced plasmas. When laser pulses with peak intensities 1019 W cm−2 and different durations (e.g.

Formulation of radiation temperature in hohlraums with large radiation energy loss

Autor: Guangyu Wang, Tieqiang Chang

Publikováno v: Physics of Plasmas. 8:1659-1663

This paper describes the radiation temperature of a hohlraum with large radiation energy loss. The hohlraum radiation temperature is crucial for indirect drive laser fusion and the radiation energy loss induced by the laser entrance hole or in other

Improved calculation for ion configuration distribution from the average-atom model

Autor: Wenbing Pei, Tieqiang Chang

Publikováno v: Journal of Quantitative Spectroscopy and Radiative Transfer. 64:15-23

An improved binomial statistical formula to calculate ion configuration distribution from the average-atom model is presented, in which the interaction between bound electrons is taken into account. The distribution of ion configuration given by the

Deducing Plasma Density Profile From Stimulated Raman Scattering Spectrum

Autor: Jiatai Zhang, Weixing Wang, Tieqiang Chang

Publikováno v: Chinese Physics Letters. 11:416-419

A new feasible approach for diagnosing plasma density profile is given in this paper. Plasma density profiles of some hohlraum targets are obtained by comparing theoretical and experimental results of the stimulated Raman scattering (SRS) spectrum. T
