Physical Model of Cyclotron Damping The Physics of Flu ( The method readily reveals which particles dominate the interaction and yields insight into the damping mechanism.

In contrast to conventional treatments of the problem via the Vlasov equation, the period of time one must wait for the asymptotic forms to be valid is Cited by: 4.

The parameter K is different depending on substances. In the ideal two-band model, K = −1 irrespective of substances, as shown in ().In bulk GaAs, K = − derived from the three-level model (Palik et al., ), and values K = − or − were obtained according to the five-level model (Zawadzki et al., ).From the cyclotron resonance in GaAs heterostructures at μm.

Founded in by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.

Classical mechanics describes the motion of macroscopic objects, from projectiles to parts of machinery, and astronomical objects, such as spacecraft, planets, stars and galaxies. If the present state of an object is known it is possible to predict by the laws of classical mechanics how it will move in the future (determinism) and how it has moved in the past (reversibility).

The characteristics of electron Bernstein wave propagation and damping are very different depending on whether the electron cyclotron harmonic resonance is approached from the low- or high-field side. Other physical mechanisms-such as transit-time damping, 14 ion cyclotron damping, 43,44 stochastic ion heating, [87][88] [89] [90][91][92][93] or collisionless magnetic reconnect -are.

Two cases are investigated. In the first case the electron distribution is assumed to have a loss‐cone feature. It is found that the plasma can amplify electromagnetic waves near the electron cyclotron frequency, as expected.

However, the growth rate is significantly larger than that used in an approximate calculation in which a slightly different physical model was by: A physical model of the solar transition region and corona is presented, The heating is assumed to be due to cyclotron-resonant damping of the waves near the local ion gyrofrequency.

The underlying physical principles are presented first, followed by macroscopic or microscopic theories. Although quantum mechanical theories are given, a phenomenological approach is emphasized.

More than half the book is devoted to a discussion of strongly coupled dipole systems, where the molecular field theory is emphasized. Words, drawings or sketches, physical models, computer programs, or mathematical formulas can be used for this purpose.

In other words, modeling activity can be done in several languages, often simultaneously. A mathematical model is a representation in mathematical terms of the behavior of real devices and objects.

Two predominant pathways for the loss of ICR signals are thought to include damping of cyclotron motion, in which ions lose kinetic energy and radially damp toward the center of the ICR cell, and dephasing of ion coherence, in which ions of like cyclotron frequency become distributed out of phase at similar cyclotron radii.

A particular strength of the book is its discussion of the various models used to describe plasma physics and the relationships between them. These include particle orbit theory, fluid equations, ideal and resistive. It is surprising that such a model works for plasmas, which generally have infrequent collisions.

But we shall see that there is a reason for this. In the greater part of this book, we shall be concerned with what can be learned from the fluid theory of plasmas. A more refined 53.
