When the high-energy particle beams converge at the common focal region, the resulting plasma ball is sufficiently dense and hot that a thermonuclear fusion reaction is instigated and thereafter sustained by the energy release accompanying the fusion reactions. Optionally, laser beams or other input energy devices may also be oriented around and toward the common focal region to direct high-energy laser beams at the plasma ball to assist with instigation of the fusion reaction. | 03-07-2013 |
