Beam Cyclotron Instability in the Magnetopause-Boundary Layer Region [PDF]

, 1982
86-87The possibility of beam cyclotron instability in the magnetopause-boundary layer region as a source for the observed fluctuations in the kHz range in the electric field is examined.

Simulations of ion cyclotron emission from energetic ions in DIII-D tokamak plasmas [PDF]

Ion cyclotron emission (ICE) was the first collective radiative instability, driven by confined fusion-born ions, that was observed from deuterium-tritium plasmas in both JET and TFTR.

Electrostatic ion cyclotron instability near threshold [PDF]

, 1986
By drawing an electron current through a plasma to a variably biased conducting button, the electrostatic ion cyclotron instability is excited, consistent with predictions of Drummond and Rosenbluth [Phys. Fluids 5, 1507 (1962)]. Recent results show that

Electron-cyclotron maser instability driven by a loss-cone distribution

, 2011
[[abstract]]It is shown that the electron-cyclotron maser instabilities may readily be excited in a plasma with a loss-cone distribution when the electron temperature exceeds a few tens of kiloelectronvolts.

Numerical simulation of unconstrained cyclotron resonant maser emission [PDF]

, 2014
When a mainly rectilinear electron beam is subject to significant magnetic compression, conservation of magnetic moment results in the formation of a horseshoe shaped velocity distribution.

The electrostatic ion-cyclotron instability excited by a current to a strip collector

, 1986
The electrostatic ion-cyclotron instability is excited in a single-ended Q-machine by drawing an electron current to a strip collector crossing the entire plasma column.

Collisional effects on the electrostatic dust cyclotron instability

, 1999
A kinetic analysis of the electrostatic dust cyclotron instability in a weakly ionized collisional dusty plasma is presented. In a plasma with negatively charged dust and a current along the magnetic field B, it is found that the instability can be

Feedback stabilization of drift cyclotron loss cone instability by modulated electron sources

, 1981
It is shown that the drift cyclotron loss cone instability can be suppressed by modulating electron density within the plasma. With the feedback in +90° phase the critical density gradient needed for the onset of the drift cyclotron loss cone instability
