Equations of Motion Near Cyclotron Resonance

چکیده
This work compares several versions of the equations motion for a test particle encountering cyclotron resonance with single, field-aligned whistler mode wave. The gyro-averaged Lorentz equation produces both widespread phase trapping (PT) and “positive bunching” low pitch angle electrons by large amplitude waves. Approximations allow Hamiltonian description to be reduced single pair conjugate variables, which can account PT as well bunching at moderate angle, has recently been used investigate this unexpected bahavior angle. Here, numerical simulations using Hamiltonian-based are compared. Similar behavior is found in each case.

Wave dispersion near cyclotron resonance in pulsar plasmas.
In a standard pulsar model, the radio emission is produced in the relativistic, strongly magnetized electron-positron plasma in the polar-cap region of the magnetosphere. Waves are generated well below the cyclotron frequency and must propagate through the cyclotron resonance region where they are affected by the resonance. Wave dispersion near the cyclotron resonance is discussed in the formal...
متن کاملCyclotron Resonance and Quasiparticles
This introductory paper contains personal perspectives about the importance of cyclotron resonance in forming our modern view of solids. The papers following this one will discuss the discovery, refinements, and some of the latest developments. Although I will touch on some of these subjects, I leave the details to the other authors and in the main focus on the conceptual impact of the work. I ...
متن کاملIn Ion-cyclotron Resonance Heating
We determine the conditions under which the damping of the fast Alfven wave, used in the heating of tokamak plasmas, can be described by the geometrical optics approximations. Also, for these conditions, we derive an analytical formula which explicitly determines the amount of energy which is damped onto the plasma particles by the fast wave. The conditions for the validity of the geometrical o...
