“…These thresholds are significantly reduced in comparison with the ignition thresholds at x = 0 for the solid advanced fuels. [12,22] The ignition energy flux density E * t for the x= 0 layers is obtained as E tp− 11 B * = 1×10 13 J/m 2 and E tp− 7 Li * = 2.5×10 13 J/m 2 at T * p− 11 B = 87 keV and T * p− 7 Li = 69 keV, respectively. This reduction of the ignition threshold is an important step in favor of the ignition of non-radioactive fuels.…”

“…The in-depth plasma block ignition is a new method for the ignition of solid advanced fuels. [5] Due to the low cross section, the ignition of the advanced fuels would be difficult with the plasma block method, [10][11][12] and controlled complementary mechanisms are needed. Therefore, the fusion conditions are met by the compression of the fuel by another laser with a longer duration pulse and the generated shock wave by impacting the plasma block with the solid fuel.…”

An accelerated skin layer may be used to ignite solid state fuels. Detailed analyses were clarified by solving the hydrodynamic equations for nonlinear force driven plasma block ignition. In this paper, the complementary mechanisms are included for the advanced fuel ignition: external factors such as lasers, compression, shock waves, and sparks. The other category is created within the plasma fusion as reheating of an alpha particle, the Bremsstrahlung absorption, expansion, conduction, and shock waves generated by explosions. With the new condition for the control of shock waves, the spherical deuterium-tritium fuel density should be increased to 75 times that of the solid state. The threshold ignition energy flux density for advanced fuel ignition may be obtained using temperature equations, including the ones for the density profile obtained through the continuity equation and the expansion velocity for the r ≠ 0 layers. These thresholds are significantly reduced in comparison with the ignition thresholds at x = 0 for solid advanced fuels. The quantum correction for the collision frequency is applied in the case of the delay in ion heating. Under the shock wave condition, the spherical proton-boron and proton-lithium fuel densities should be increased to densities 120 and 180 times that of the solid state. These plasma compressions are achieved through a longer duration laser pulse or X-ray.
