Resonance mechanism for energization of electrons in magnetoplasma. III

Abstract

The well-known cyclotron resonance mechanism has been studied and energization of electrons in the magnetosphere has been explored. The relativiatic variation of electron mass in the resonance process hag been considered and the consequence of neglecting the relativistic electron mass variation has been discussed. At or near resonance the electron motion conforms with the motion of electrons in a potential well. Calculating the shape of the pseudo-potential for the magnetospheric plasma we have calculated the energy gained by the electrons. It is seen that 1 ov electron resonating with the electromagnetic wave (w equals; 107 rad sec-1 and E = 10-7 e.s.u.) acquires 1 Mev energy after 1.88 see. The geophysical effect of the proposed energization is discussed. © 1971, Taylor & Francis Group, LLC.
