ANALYSIS OF THE RETROGRADE HYDROGEN BORON FUSION GAINS AT INERTIAL CONFINEMENT FUSION WITH VOLUME IGNITION

The very clean nuclear fusion reaction of hydrogen and boron-ll by ine rtial confinement arrives at conditions for power stations by volume i gnition only al compressions to 100,000 times the solid state. The ear lier (numerically) observed anomaly of decreasing gain at increasing d ensity (retrograde behavior) is analyzed and the reason clarified: the strong stopping power mechanism, based on Gabor's collective model, i s reaching its limit of too small Debye lengths at the extremely high densities because of the optimum temperature in the range of 30 keV du e to the reabsorption of the bremsstrahlung. The relativistic correcti on of the bremsstrahlung for the always much higher temperatures after volume ignition is included from Maxon's model.
