A one-dimensional model describing the radiation-driven implosion in cylindrical hohlraums is proposed in this article. For the model, the radiation flux boundary condition is composed of both the equilibrium and the nonequilibrium parts by means of the experimentally measured radiation temperature and the nonequilibrium x-ray spectra emitted from laser spots. The correctness of the model is guaranteed by a criterion, the capsule-absorbed radiation energy inferred from the hohlraum radiation theory, which is independent of any implosion simulation [Chang et al., Phys. Plasmas 11, 4286 (2004)]. In this article the model is applied to the implosion experiments performed at the Shenguang II laser facility [Zunqi et al., Chin. J. Lasers, B10, 6 (2001)], and the neutron yields are consistent with the experimental data if the hydrodynamic instability is appropriately considered. [ABSTRACT FROM AUTHOR] |
