“…Up to this stage (Hora et al, 2010;Lalousis et al, 2013), the computations were still pessimistically using only binary reactions as always applied for fusion. The necessary further improvement beyond the binary reactions for HB11, however, is essential for the favorable nonthermal ps-block ignition described in the following.…”

Exceptionally high reaction gains of hydrogen protons measured with the boron isotope 11 are compared with other fusion reactions. This is leading to the conclusion that secondary avalanche reactions are happening and confirming the results of high-gain, neutron-free, clean, safe, low-cost, and long-term available energy. The essential basis is the unusual nonthermal block-ignition scheme with picosecond laser pulses of extremely high powers above the petawatt range.

“…This was experienced by extending the results derived for relativistic ion beams [8] following the application of petawatt to exawatt laser pulses for a new scheme of compact laser-driven compact magnetic fusion device. Laser-driven proton beam acceleration by high power laser beam interaction with ultrathin solid target is under investigation in the existing kJ/PW laser facilities as the GEKKO-LFEX [25,26] , ORION [27] and PETAL [28,29] .…”

“…The application of the nonthermal, efficient ultrahigh acceleration for a new approach for nuclear fusion [7] led to an alternative kind of shock ignition [8,9] . Parallel to these ultrahigh accelerations, ultrahigh ion current densities were detected [10] in the space charge neutral directed motion of the plasma blocks with homogeneous high ion energies exceeding ion current densities of 10 12 A cm −2 .…”

The application of laser pulses with psec or shorter duration enables nonthermal efficient ultrahigh acceleration of plasma blocks with homogeneous high ion energies exceeding ion current densities of 10 12 A cm −2 . The effects of ultrahigh acceleration of plasma blocks with high energy proton beams are proposed for muon production in a compact magnetic fusion device. The proposed new scheme consists of an ignition fusion spark by muon catalyzed fusion (µCF) in a small mirror-like configuration where low temperature D-T plasma is trapped for a duration of 1 µs. This initial fusion spark produces sufficient alpha heating in order to initiate the fusion process in the main device. The use of a multi-fluid global particle and energy balance code allows us to follow the temporal evolution of the reaction rate of the fusion process in the device. Recent progress on the ICAN and IZEST projects for high efficient high power and high repetition rate laser systems allows development of the proposed device for clean energy production. With the proposed approaches, experiments on fusion nuclear reactions and µCF process can be performed in magnetized plasmas in existing kJ/PW laser facilities as the GEKKO-LFEX, the PETAL and the ORION or in the near future laser facilities as the ELI-NP Romanian pillar.Keywords: alpha heating effect; high energy density physics; laser plasmas interaction; laser proton acceleration high energy density physics; muon catalyzed fusion; ultra-intense; ultra-short pulse laser interaction with matters

“…Indeed this was related to the reheat based on Denis Gabors's (1952) collective stopping power used in the computations for volume ignition (Hora, 1991) since 1978. This collective stopping was used also in the alternative picosecond nonlinear force driven block ignition scheme with ultrahigh plasma acceleration (Hora, 2009;Hora et al, 2012;Lalousis et al, 2013). The predominance of the Gabor collective effect at very high plasma densities was measured also in other in another connection (Hoffmann et al, 1990).…”
