“…The easy operation with one beam ignition should then permit a reactor with one shot per second [44] and sufficiently fast localisation of the reaction unit using presently available technology for low cost power generation [37] [45]. The now presented results show an increase of the HB11 fusion gains by more than nine orders of magnitudes above the classical value [41].…”

“…In the worst case no charge of the reaction unit against the wall can be used however resulting in a lower efficiency of the power production via thermal energy conversion from the wall. The specific evaluation of elastic collisions of the generated alphas with protons and boron nuclei [41] documented how the hydrogen nuclei receive an energy within a wide range around 600 keV energy, Figure 5, for reacting with the 11 B nuclei at nearly ten times higher fusion cross sections compared with all known other fusion reactions [8], to produce each three alphas etc. for the avalanche.…”

“…for the avalanche. The measurements [22] with the nuclei for the energetic HB11 reactions on the background of less than few ten eV background plasma, could be theoretical reproduced in details [41]. This shows the need to explore this kind of non-ideal [42] and non-neutral [43] plasmas.…”

Fusion of hydrogen with the boron Isotope 11, HB11 at local thermal equilibrium LTE, is 10 5 times more difficult than fusion of deuterium and tritium, DT. If -in contrastextreme non-equilibrium plasma conditions are used with picoseconds laser pulses of more than 10PW power, the difficulties for fusion of HB11 change to the level of DT. This is based on a non-thermal transfer of laser energy into macroscopic plasma motion by nonlinear (ponderomotive) forces as theoretically predicted and experimentally confirmed as "ultrahigh acceleration". Including elastic nuclear collisions of the alpha particles from HB11 reactions results in an avalanche process such that the energy gains from HB11 fusion is nine orders of magnitudes above the classical values. In contrast to preceding laser fusion with spherical compression of the fuel, the side-on direct drive fusion of cylindrical uncompressed solid boron fuel trapped by magnetic fields above kilotesla, permits a reactor design with only one single laser beam for ignition within a spherical reactor. It appears to be potentially possible with present day technology to build a reactor for environmentally fully clean, low-cost and lasting power generation.

“…The publication of the computations [40] was just at the same time as the generation of one billion HB11 reactions [39] by irradiating 500 Joule laser pulses of 200 ps duration on extremely boron enriched silicon targets used in semiconductor studies [71]. The comparison with fusion gains of DT [57][58] permitted [42] the proof of the avalanche mechanism at plane geometry [53] [72] and was supported [73] by the evaluation of the elastic collisions and an subsequent reactions of HB11 within the background plasma of more than 10 eV temperature of solid state density [38][73][74] [75].…”

Extreme laser pulses driving non-equilibrium processes in high density plasmas permit an increase of the fusion of hydrogen with the boron isotope 11 by nine orders of magnitude of the energy gains above the classical values. This is the result of initiating the reaction by non-thermal ultrahigh acceleration of plasma blocks by the nonlinear (ponderomotive) force of the laser field in addition to the avalanche reaction that has now been experimentally and theoretically manifested. The design of a very compact fusion power reactor is scheduled to produce then environmentally fully clean and inexhaustive generation of energy at profitably low costs. The reaction within a volume of cubic millimetres during a nanosecond can only be used for controlled power generation.

“…[7][8][9] In the last decade a renewed interest on this topic has been shown through the possibility to trigger such nuclear reactions by using high power pulsed laser interacting with solid B-enriched targets. [10][11][12][13][14][15][16][17] Charged energetic particles are routinely used in medicine, in particular in cancer therapy. Currently hadron-therapy is becoming one of the most important medical procedures to treat solidified tumors instead of traditional radiotherapy treatments.…”

Prompt gamma ray diagnostics and enhanced hadron-therapy using neutron-free nuclear reactions

We propose a series of simulations about the potential use of Boron isotopes to trigger neutron-free (aneutronic) nuclear reactions in cancer cells through the interaction with an incoming energetic proton beam, thus resulting in the emission of characteristic prompt gamma radiation (429 keV, 718 keV and 1435 keV). Furthermore assuming that the Boron isotopes are absorbed in cancer cells, the three alpha-particles produced in each p-11 B aneutronic nuclear fusion reactions can potentially result in the enhancement of the biological dose absorbed in the tumor region since these multi-MeV alpha-particles are stopped inside the single cancer cell, thus allowing to spare the surrounding tissues. Although a similar approach based on the use of 11 B nuclei has been proposed in [1], our work demonstrate, using Monte Carlo simulations, the crucial importance of the use of 10 B nuclei (in a solution containing also 11 B) for the generation of prompt gamma-rays, which can be applied to medical imaging. In fact, we demonstrate that the use of 10 B nuclei can enhance the intensity of the 718 keV gamma-ray peak more than 30 times compared to the solution containing only 11 B nuclei. A detailed explanation of the origin of the different prompt gamma-rays, as well as of their application as real-time diagnostics during a potential cancer treatment, is here discussed.
