Stochastic heating and acceleration of electrons in colliding laser fields in plasma.
Zheng-Ming Sheng,Zheng-Ming Sheng,K. Mima,Yasuhiko Sentoku,M. S. Jovanović,Toshihiro Taguchi,Jie Zhang,Jürgen Meyer-ter-Vehn +7 more
TL;DR: A mechanism that leads to efficient acceleration of electrons in plasma by two counterpropagating laser pulses is proposed, triggered by stochastic motion of electrons when the laser fields exceed some threshold amplitudes, as found in single-electron dynamics.

Control of an electron beam using strong magnetic field for efficient core heating in fast ignition
Tomoyuki Johzaki,Toshihiro Taguchi,Yasuhiko Sentoku,Atsushi Sunahara,Hideo Nagatomo,Hitoshi Sakagami,Kunioki Mima,Shinsuke Fujioka,H. Shiraga +8 more
TL;DR: In this article, the fast electron beam guiding using externally applied longitudinal magnetic fields was proposed for enhancing the core heating efficiency in electron-driven fast ignition. But the beam guiding performance in the collisional dense plasma was not evaluated.

Tomoyuki Johzaki,Toshihiro Taguchi,Yasuhiko Sentoku,Atsushi Sunahara,Hideo Nagatomo,Hitoshi Sakagami,K. Mima,Shinsuke Fujioka,Hiroyuki Shiraga +8 more
TL;DR: In this article, the fast electron beam guiding using externally applied longitudinal magnetic fields was proposed for enhancing the core heating efficiency in electron-driven fast ignition, which demonstrated the sufficient beam guiding performance in the collisional dense plasma by kT-class external magnetic fields for the case with moderate mirror ratio.

TL;DR: Cluster heating by a strong laser field is studied using a particle-in-cell code (PIC) for a range of intensities and cluster sizes and above a threshold intensity, heating is dominated by a nonlinear resonant absorption process.

TL;DR: The second series experiment of FIREX-I, from late 2010 to early 2011, has demonstrated a high (>10%) coupling efficiency from laser to thermal energy of the compressed core, suggesting that the ignition temperature can be achieved at laser energy below 10 kJ as discussed by the authors.
