Evidence of jovian active longitude: 1. Efficiency of cyclotron maser instability

Pfc/ja-85-4 Free Electron Laser or Cyclotron Maser Instability?

An analysis of recent free electron laser experiments in combined wiggler and strong axial magnetic fields shows that near resonance, Q,,=kwv,,, the proximity of the cyclotron maser instability precludes an unambiguous identification of the radiation mechanism ( 2,, is the cyclotron frequency in the axial field, kw is the wiggler wavenumber, and v,, the axial electron velocity).

Cyclotron Maser Emission from Blazar Jets?

We consider the production of electron cyclotron maser emission by lowdensity, highly magnetized plasmas in relativistic jets. The population inversion required to drive cyclotron maser instability could occur in localized, transient sites where hydromagnetic instabilities, shocks, and/or turbulence lead to magnetic mirroring along current-carrying flux tubes. The maser is pumped by the convers...

Pfc/ja-80-23 Influence of Wall Impedance on the Electron Cyclotron Maser Instability

Confirmation of the Electron Cyclotron Maser Instability as the Dominant Source of Radio Emission from Very Low Mass Stars and Brown Dwarfs

We report on radio observations of the M8.5 dwarf LSR J1835+3259 and the L3.5 dwarf 2MASS J00361617+1821104, which provide the strongest evidence to date that the electron cyclotron maser instability is the dominant mechanism producing radio emission in the magnetospheres of ultracool dwarfs. As has previously been reported for the M9 dwarf TVLM 513-46546, periodic pulses of 100% circularly pol...
