“…Electromagnetic radiation fluxes and beams of charged particles due to the development of self-modulation instability can be broken into a chain of particle bunches (see [9 -11]) or a chain of electromagnetic pulses (see [12]), which excite a wakefield in the plasma, which effectively accelerate charged particles (see [13 -16]). Also, due to the development of self-modulation instability, electromagnetic radiation can be broken down into a chain of electromagnetic pulses that excite a wakefield in the plasma, which effectively accelerates charged particles, and they can continue to excite the wakefield and accelerate charged particles to even higher energies (see [17,18]). Also, in a nonequilibrium current plasma or a plasma with particle flows, a strong electric double layer can form (see [8]), which accelerates charged particles to high energies.…”

The acceleration of particles to the high energy is one of the key issues of solar physics, cis-lunar irradiations, astrophysics, and astroparticle physics. With the development of space astronomy, people started to realize that plasma disturbances in solar flares, Earth’s magnetosphere, and interplanetary space can also produce a large population of non-thermal particles. Cosmic ray promotion i.e. selective energization of matter in the cosmos requires, as on earth, three distinct stages: ionization, injection and acceleration to high energy. Supernova remnants and stellar winds of massive stars grouped in associations appear to be excellent celestial accelerators or re-accelerators through the shock waves they induce in their superbubbles. The injection of ions seems devoted to stars, except the smaller ones. In cosmic several mechanisms lead charged particle acceleration. Electrons are accelerated in direction of Earth’s poles by long train of electric double layers of small amplitudes. Charged particles are accelerated by the pondermotive force of electromagnetic radiation. Also, in a nonequilibrium current plasma or a plasma with particle flows, a strong electric double layer can be formed, which accelerates charged particles to high energies. The reconnection of the magnetic field lines also leads to the acceleration of charged particles.
