Cut-off near the ion-ion hybrid resonance frequency and a resonance at the higher of the two ion cyclotron frequencies. This branch will be called “the ion-ion hybrid wave”.

The two branches can be seen clearly in Fig. At low k- the ion-ion hybrid wave interacts with the fast (compressional Alfven) wave as shown in Fig.

Wave Cited by: In ion cyclotron range of frequency experiments, we have simultaneously measured the incident fast wave and the mode converted waves in the mode conversion region in D(3He) plasmas using an.

Abstract. For the ion-ion hybrid resonance it is shown that: (1) the energy absorption occurs via a sequence of mode conversions; (2) a poloidal field component normal to the ion-ion hybrid mode conversion surface strongly influences the mode conversion process so that roughly equal electron and ion heating occurs in the present proton-deuterium experiments, while solely electron heating is.

A time-dependent one-dimensional fluid model was developed to study the dynamics of a positive ion-negative ion ion-ion plasma under the influence of a rf bias voltage.

Ion cyclotron drift waves propagating across a density gradient and a magnetic field have been excited externally in a two-ion species plasma, with it Cited by: 2. The project developed theoretical and numerical descriptions of the properties of ion-ion hybrid Alfvén resonators that are expected to arise in the operation of a fusion reactor.

The methodology and theoretical concepts were successfully compared to observations made in basic experiments in the. The ion–ion hybrid resonant frequency is slightly lower than the ion–ion hybrid cutoff frequency, ω resonance.


Heating in Toroidal Plasmas and wave propagation were observed at frequencies above the second harmonic of the ion cyclotron frequency for single species hydrogen and for multi-species (deuterium/hydrogen) plasmas. RF current drive by high-phase-velocity slow modes near the ion-ion hybrid resonance is investigated.

The generation of ion-acoustic solitary waves is investigated in a nonuniform multicomponent collisional plasma sheath containing cold ions and Boltzmann electrons to probe the formation and physics of modulation of nonlinear ion-acoustic waves. The new model for the plasma is adapted to include the effects of ion production-loss and momentum loss terms due to ion-neutral Author: Nora Nassiri-Mofakham.

Ion acoustic solitons and double layers are studied in a collisionless plasma consisting of cold heavier ion species, a warm lighter ion species, and hot electrons having Boltzmann distributions by Sagdeev pseudo-potential technique.

In contrast to the previous results, no double layers and super-solitons are found when both the heavy and lighter ion species are treated as by: Borg, G.C.

low frequency noise (~50Hz). This time to reduce the (low frequency) noise without sacrificing sensitivity, also to rise the frequency limit of LC resonance circuit, the divergence-free magnetic probe system is designed.

This system consists of the polyhedron covered with multiple coils. For example, if it is a cube,File Size: 12MB. The strength of the book is the comparison of the similarities and differences in the plasma interaction of Venus, Mars and Titan; such comparisons have not yet been published. This volume is aimed at graduate students and researchers working in planetary science and space physics.

We present the status of the installation and commissioning of the LEBT, and compare particle dynamics simulations with preliminary measurements of the H - beam. Two ion energy settings (i.e.

anode grid voltages) are: 8 (low) or 12 eV (high). The ion energy setting affects the magnitude of the ion signals collected (i.e. sensitivity of the spectrometer) and limits the ultimate resolution of the mass filter.

The measured wave number and frequencies are compared with the theoretical dispersion relations. These observations confirm the existence of ion-ion co-stream instability in sheath-presheath of two-ion species plasma. An Entrance Region Mass Transfer Experiment.
