Particle acceleration by MHD shock turbulence

Open publisher page 0 citations

Abstract

A statistical mechanism is proposed for the acceleration of charged particles in collisions with MHD shock waves; the magnetic field in the shock wave is assumed to form an angle. This acceleration mechanism is much more effective than the Fermi mechanism and can produce particles with extremely high energy. Calculations are also carried out for the acceleration of particles at luminescent shock fronts; these calculations pertain to the emission of hard electromagnetic radiation in a contracting plasma.
