АНАЛИЗ ЗАВИСИМОСТИ СЕФОТРОННОГО УСКОРЕНИЯ ЭЛЕКТРОНОВ В ПЛАЗМЕ ОТ ФАЗОВОЙ СКОРОСТИ ЭЛЕКТРОМАГНИТНОЙ ВОЛНЫ

THE ANALYSIS OF ELECTRONS SURFATRON ACCELERATION IN PLASMA IN THE DEPENDENCE ON ELECTROMAGNETIC WAVE PHASE VELOCITY

On the basis of numerical calculations it is considered ultrarelativistic acceleration of electrons in space plasma by the electromagnetic wave propagating across the external magnetic field. The dependence of acceleration efficiency on wave phase velociy is studied and it has been shown that the acceleration efficiency is much more for the large value of wave phase velocity. The transition from small wave phase velocity to the large one takes place under small decreasing of wave frequency. The dynamics of accelerated electron velocity and impulse components are investigated also.
