Quasi-one-dimensional particle-in-cell simulation of magnetic nozzles
نویسندگان
چکیده
A method for the quasi-one-dimensional simulation of magnetic nozzles was developed and simulations of a magnetic nozzle were performed. The effects of the density variation due to plasma expansion and the magnetic field forces on ion acceleration were investigated. The density variation only weakly affects ion acceleration. Magnetic field forces acting on the electrons were found to be responsible for the formation of potential structures which accelerate ions. The formation of a high energy ion beam is seen due to ion acceleration. Strongly diverging magnetic fields drive more rapid potential drops.

Quasi-one-dimensional code for particle-in-cell simulation of magnetic nozzle expansion
The formulation and validation of a novel quasi-one-dimensional particle-in-cell code for the simulation of magnetic nozzles is presented. Quasi-one-dimensional effects are included through virtual displacements of magnetized particles from the axis of symmetry and cross-sectional area variation according to preservation of magnetic flux. A modified, semi-implicit Boris algorithm is developed f...

In this paper, the Hartree-Fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. The bare coulomb interaction between electrons has been assumed. For this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...

متن کاملA Three Dimensional Simulation of Solitary Waves in the Laser Wake
Three dimensional relativistic electromagnetic sub-cycle solitons were observed in Particle-in-Cell simulations of an intense short laser pulse propagation in an underdense plasma. Their structure resembles that of an oscillating electric dipole with a poloidal electric field and a toroidal magnetic field that oscillate in-phase with the electron density with frequency below the Langmuir freque...
