“…The HB11 plasma contains then a component of the lower density of a fluid of alpha particles with the elastic collisions of boron nuclei at around 600 keV energy. This is a typical non-ideal plasma known from other applications [50] .…”

(2015)) for the combination of the non-thermal block ignition using ultrahigh intensity laser pulses of picoseconds duration. The ultrahigh acceleration above 10 20 cm s −2 for plasma blocks was theoretically and numerically predicted since 1978 (Hora, Physics of Laser Driven Plasmas (Wiley, 1981), pp. 178 and 179) and measured (Sauerbrey, Phys. Plasmas 3, 4712 (1996)) in exact agreement (Hora et al., Phys. Plasmas 14, 072701 (2007)) when the dominating force was overcoming thermal processes. This is based on Maxwell's stress tensor by the dielectric properties of plasma leading to the nonlinear (ponderomotive) force f NL resulting in ultra-fast expanding plasma blocks by a dielectric explosion. Combining this with measured ultrahigh magnetic fields and the avalanche process opens an option for an environmentally absolute clean and economic boron fusion power reactor. This is supported also by other experiments with very high HB11 reactions under different conditions (Labaune et al., Nature Commun. 4, 2506).

“…As a result, the ratio of electron kinetic energy to electrostatic potential energy falls dramatically, the Debye length of the plasma falls abruptly below the Wigner-Seitz radius of xenon, and the plasma enters a regime of strong correlation. In this regime, a number of the assumptions of Debye-Hückel screening model break down, and the Debye length loses its meaning as a screening distance [43]. If the plasma cools sufficiently, screening lengths can become complex, and result in oscillatory electron-ion correlation functions [44,45].…”

Interaction of intense vuv radiation with large xenon clusters

The interaction of atomic clusters with short, intense pulses of laser light to form extremely hot, dense plasmas has attracted extensive experimental and theoretical interest. The high density of atoms within the cluster greatly enhances the atom-laser interaction, while the finite size of the cluster prevents energy from escaping the interaction region. Recent technological advances have allowed experiments to probe the laser-cluster interaction at very high photon energies, with interactions much stronger than suggested by theories for lower photon energies. We present a model of the laser-cluster interaction which uses non-perturbative R-matrix techniques to calculate inverse bremsstrahlung and photoionization cross sections for Herman-Skillman atomic potentials. We describe the evolution of the cluster under the influence of the processes of inverse bremsstrahlung heating, photoionization, collisional ionization and recombination, and expansion of the cluster. We compare charge state distribution, charge state ejection energies, and total energy absorbed with the Hamburg experiment of Wabnitz et al. [Nature 420, 482 (2002)] and ejected electron spectra with Laarmann et al. [Phys. Rev. Lett. 95, 063402 (2005)].

“…The fact is that direct photoionization takes the place of thermal collisional ionization beginning with intensities of 10 21 -10 22 W/cm 2 . In this case, the photoelectrons escape from a cluster to violate the fundamental condition of plasma electroneutrality [79], resulting in the generation of intense electric fields. A "Coulomb explosion" occurs, with the effect that the ions are accelerated to high ( 1 MeV) energies [70,157,191] and fusion neutrons are generated [59].…”
