Ion heating in laser interacting with magnetized plasma

نویسندگان

چکیده

The ion heating mechanism in the context of laser interacting with plasma immersed a strong magnetic field is studied. chosen to be for electromagnetic propagation inside governed by magnetized dispersion relation. Both X and RL mode configurations have been studied detail using Particle - In Cell (PIC) simulations. It shown that energy absorption process resonant wherein frequency matches an underlying plasma. For configurations, these correspond lower hybrid cyclotron resonance, respectively. absorption, however, found most efficient at frequencies close but not exactly matching resonance frequency. An understanding same has provided. role polarization detail.

Selective Heating of Helium Ion in Magnetized Sheet Plasma

Ion cyclotron resonance heating in the magnetized sheet plasma is studied experimentally in a linear plasma device, TPD-SheetIV. We have demonstrated the ICRH of the helium or helium/hydrogen mixture sheet plasma by the RF electrodes of two parallel plates, sandwiching the sheet plasma. Measurements of the ion temperature in the plasma were carried out by a Faraday cup. In addition, the ion den...

Ion kinetics in a magnetized plasma source

There are regimes of plasma source operation in which the ion motion is controlled by the ambipolar electric eld and ion-atom collisions. This paper presents a derivation of the corresponding ion distribution function and plasma density pro les in the source for a given electron temperature and a given gas ionization rate. Conditions are discussed under which the ion ux is predominantly radial ...

Investigation of Dust-Ion Acoustic Waves in a Magnetized Collisional Dusty Plasma with Kappa Distribution Function for Electrons

The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...

Ion Dynamics in Multiple Electrostatic Waves in a Magnetized Plasma

A general theoretical study of the dynamics of ions interacting with multiple elec-trostatic waves, propagating perpendicularly to a uniform magnetic field, is performed. For appropriately chosen frequencies and wavenumbers we discover a new nonlinear phenomenon of coherent acceleration (or deceleration) which energizes (or extracts energy from) ions. Ions whose initial energies are below the l...

Classical impurity ion confinement in a toroidal magnetized fusion plasma.

High-resolution measurements of impurity ion dynamics provide first-time evidence of classical ion confinement in a toroidal, magnetically confined plasma. The density profile evolution of fully stripped carbon is measured in MST reversed-field pinch plasmas with reduced magnetic turbulence to assess Coulomb-collisional transport without the neoclassical enhancement from particle drift effects....
