Thermonuclear Reaction Wave in High-Density Plasma
Thermonuclear reaction waves in plasmas have recently attracted considerable attentions in connection with the laser-induced thermonuclear fusion. In a highly compressed laser plasma, the burning process may develop as follows1: The inner region of a D-T sphere is compressed adabatically by a factor 103 to 104 above its solid density, and the center of the compressed fuel is brought to an ignition temperature, while the rest of the fuel remains relatively cold. Then, the enrgy produced in the ignited and burning central region of the fuel can heat the surrounding cold fuel sufficiently for ignition to occur. This process leads to the formation of a self-driven reaction wave which can propagate radially outwards igniting the cold fuel.
