RT Journal Article ID 1c87bf157ddcd6f3 A1 Kirichenko, Yu. V. T1 Generation and Amplification of Electromagnetic Waves by a Tubular Plasma Beam in Crossed Radial Electrostatic and Axial Magnetic Fields in Free Space JF Telecommunications and Radio Engineering JO TRE YR 1999 FD 1999-08-01 VO 53 IS 7-8 SP 102 OP 107 AB A possible mechanism of generation and amplification of electromagnetic waves by plasma rotating in crossed axial magnetic and radial electrostatic fields is investigated theoretically. A dispersion relation describing the wave-electron interaction has been derived. It is shown that generation and amplification of waves is possible under the Cerenkov resonance conditions.
