“…We show here that, without consideration of the practicality, for a particular parameter regime, Fermi degeneracy plays an important role in reducing the alpha particle stopping, ion-electron collisions and the bremsstrahlung, so that self-burning is possible. The optimal regimes are characterized by an electron temperature much lower than the 80 KeV suggested by Eliezer and Martinez-Val [5,8].…”

“…For inertial confinement fusion using P-B-11, there have been several theoretical attempts to generate a detonation wave [5,[8][9][10]. Martinez-Val and Eliezer [8] showed that compressed fuel can be burned by an expanding ion fusionburning wave preceded by an electron-conduction heat detonation wave.…”

“…Martinez-Val and Eliezer [8] showed that compressed fuel can be burned by an expanding ion fusionburning wave preceded by an electron-conduction heat detonation wave. A large gap between the electron temperature T e ∼ = 80 KeV and the ion temperature T i ∼ = 200 KeV might then be achievable.…”

In a Fermi-degenerate plasma, the electronic stopping of a slow ion is smaller than that given by the classical formula, because some transitions between the electron states are forbidden. The bremsstrahlung losses are then smaller, so that the nuclear burning of an aneutronic fuel is more efficient. Consequently, there occurs a parameter regime in which self-burning is possible. Practical obstacles in this regime that must be overcome before net energy can be realized include the compression of the fuel to an ultra dense state and the creation of a hot spot. +

“…Finally, if the size of the pellet were larger, or if the fuel were surrounded by various materials, as is the case in a realistic pellet design, the importance of radiation effects would be further enhanced. These problems illustrate the difficulty of burning advanced thermonuclear fuels, such as DT x , D 3 He, or p 11 B [9], relative to burning those containing a large tritium fraction, such as DT or 6 LiDT. Table 1: Maximum ion, electron, and radiation temperatures; final fuel burn-up fraction; and ratios of tritium content as a function of time for several radiation interaction models.…”

Inclusion of inverse Compton effects in the calculation of deuterium-deuterium burn under the extreme conditions considered by Eliezer et al. [Phys. Lett. A 243 (1998) 298] are shown to decrease the maximum burn temperature from about 300 keV to only 100-150 keV. This decrease is such that tritium breeding by the DD → T + p reaction is not sufficient to replace the small amount of tritium that is initially added to the deuterium plasma in order to trigger ignition at less than 10 keV.

“…The reasoning is that it is energetically cheaper to compress rather than to heat and the nuclear reactions are proportional to the density squared. IFE of deuterium-tritium (DT) requires high compression (>1000) and, in particular, the aneutronic fusion [4][5][6] of protonboron11 needs extremely high compression (>10 000). The high compression is achieved by shock waves and the accumulation of matter during stagnation of the implosion of the target shell.…”

In this paper we consider laser intensities greater than 10 16 W cm −2 where the ablation pressure is negligible in comparison with the radiation pressure. The radiation pressure is caused by the ponderomotive force acting mainly on the electrons that are separated from the ions to create a double layer (DL). This DL is accelerated into the target, like a piston that pushes the matter in such a way that a shock wave is created. Here we discuss two novel ideas. Firstly, the transition domain between the relativistic and non-relativistic laser-induced shock waves. Our solution is based on relativistic hydrodynamics also for the above transition domain. The relativistic shock wave parameters, such as compression, pressure, shock wave and particle flow velocities, sound velocity and rarefaction wave velocity in the compressed target, and temperature are calculated. Secondly, we would like to use this transition domain for shockwave-induced ultrafast ignition of a pre-compressed target. The laser parameters for these purposes are calculated and the main advantages of this scheme are described. If this scheme is successful a new source of energy in large quantities may become feasible.
