Measuring impact of M-band and soft X-rays on radiation-driven ablation performance
چکیده انگلیسی
M-band and soft X-rays play different roles in radiation-driven ablation. In the SGIII-prototype laser facility, experiments were performed to deduce the absorbed M-band and soft X-rays at different angles. Both the absorbed energy and the absorption rate of the M-band and soft X-rays were studied. The results showed that the M-band (1.6-4.4 keV) and soft (0.1-1.6 keV) X-rays performed differently in radiation-driven ablation. The difference was determined by the radiation source, the state of the ablator, and the field of view. A time-varying radiation source, the opacity change of the ablator, and fields of view at different angles were studied by using the one-dimensional multi-group radiation hydrodynamic code Multi-1D and the three-dimensional view-factor code IRAD3D. Radiation-driven ablation is the interaction between X-rays and the ablator. These studies are useful for understanding the ablation process and provide guidance for increasing the ablation rate and reducing the preheat effect.
