«coulomb explosion» of electron vortex as an energetic ion source

A new mechanism of a «Coulomb explosion» is proposed on the basis of a new model of the electron vortices in the plasma with the magnetic field, where ions are accelerated by the electric field arising due to the charge separation at the magnetic Debye radius r<inf>B</inf> ∼ B/4πen<inf>e</inf>. The origin of such explosive dynamics is the formation of «holes» in the electron density at characteristic times of the order of ω<inf>pe</inf>−1 (ω<inf>pe</inf> is the electronic plasma frequency) as a result of the generation of electronic vorticity by the Weibel instability of electromagnetic wave. Calculations of a laser pulse with intensity J ∼ 6×10<sup>18</sup> W/cm<sup>2</sup> show that the ions expand in the radial direction with velocities up to 3.5 ×10<sup>8</sup> cm/s.
