Abstract: Fast ignition for fusion energy by using petawatt-picosecond (PW-ps) laser pulses was modified due to an anomaly based on extremely clean suppression of prepulses. The resulting plasma blocks with space charge neutral ion current densities above 1011Amp/cm2may be used to ignite deuterium-tritium at densities at or little above solid state density. The difficulty is to produce extremely high energy flux densities of the blocks. Results are reported how the threshold can be reduced by a factor up to fife if the … Show more

“…After the inclusion of the inhibition factor for thermal conduction was studied (Ghoranneviss et al, 2008;Zhou et al, 2008), the detailed studies for the reduced stopping lengths for alpha particles are presented here including a detailed description of the hydrodynamic properties with application of the generally rather complex theory of the stopping power.

“…While these questions are still under discussion for the DT case , we are first focusing on the problem of the inhibition factor F*, that means on the reduction of the thermal conductivity, as treated in details before for the DT case ; see also Hora, 2009). 1 of Ghoranneviss et al, 2008). Some authors found a value of 30 or 100 for the inhibition factor of deuterium.…”

“…The experiments with TWps laser pulses (17) well arrived at values of E * in the range of up to 10 6 J cm −2 , but it is essential that the conditions for the results of Chu (16) have to be re-examined in view of effects which were discovered later. One of these effects is the strong reduction of the thermal conductivity of the electrons by an inhibition factor (18,19). The reduction of the thermal conductivity of the electrons by the inhibition factor was discovered in an empirical way from the evaluation of experiments of laser fusion.…”
