Accelerating field excitation, occurrence and evolution of electron beam near Jupiter

Maslov, V.I.; Fomina, A.P.; Kholodov, R.I.; Levchuk, I.P.; Nikonova, S.A.; Novak, O.P.; Onishchenko, I.N. (Вопросы атомной науки и техники, 2018)

When electron beam, formed Io-Jupiter penetrates into Jupiter plasma the beam-plasma instability develops. Then electron distribution function becomes wider by excited fields. These electrons cause UV polar light. The ...
