Low-Frequency Stability of Mirror Confined Plasmas.

Influence of radio frequency waves on the interchange stability in HANBIT mirror plasmas

Experimental and theoretical studies are made of the influence of high frequency radio frequency (rf) waves upon interchange stability in HANBIT mirror plasmas. An emphasis is put on the interchange stability near the resonance region, ω0≈Ωi, where ω0 is the angular frequency of the applied rf wave and Ωi is the ion cyclotron frequency. Recent HANBIT experiments have shown the existence of the ...

Properties of non-neutral electron plasmas confined with a magnetic mirror field.

A low energy non-neutral electron plasma was confined with a magnetic mirror field and an electrostatic potential to investigate the basic confinement properties of a simple magnetic mirror trap. The mirror ratio of the magnetic field was increased up to 5. As expected the confinement time became longer as a function of the mirror ratio. The axially integrated radial density profiles in equilib...

Microstability of magnetically confined electron-positron plasmas.

It is shown that magnetically confined electron-positron plasmas can enjoy remarkable stability properties. Many of the microinstabilities driving turbulence and transport in electron-ion plasmas are absent if the density is so low that the Debye length is significantly larger than the gyroradius. In some magnetic configurations, almost complete linear stability may be attainable in large parts...

Boltzmann-Equation Simulations of Radio-Frequency-Driven, Low-Temperature Plasmas

Exchange effects in plasmas: the case of low-frequency dynamics.

Recently, there has been a surge of interest in nonequilibrium collective quantum models, where particle dispersion and spin are examples of effects taken into account. Here, we derive a kinetic plasma model containing fermion exchange effects. Exchange interactions are of great importance in many systems and have no classical analogy. Our model therefore constitutes a possible probe of collect...
