Particle-in-Cell (PIC) simulation codes have wide applicability to first-principles modeling of multidimensional nonlinear plasma phenomena, including wake-field accelerators. This review addresses both finite difference and pseudo-spectral PIC algorithms, including numerical instability suppression and generalizations of the spectral field solver. INTRODUCTION AND SUMMARY Particle-in-Cell (PIC...
Azimuthal structures in cylindrical Penning discharge are studied with 2D3V radial-azimuthal PIC/MCC model the axial magnetic field. The is self-consistently supported by ionization due to injection of electrons. It shown that steady-state can be two different regimes type observed azimuthal structures. transition between controlled mechanism energy input discharge. In first regime (low injecte...
This article is a study on the analysis of harmonics reductions and load voltage control for Vienna Rectifier (VR) with help of the Triplen Harmonic Injection (THJ) and the proportional integral controller (PIC). The sinusoidal PWM is the easiest modulation technique for AC-DC rectifiers to comprehend; however, it is not capable of entirely using the accessible DC bus source voltage. In order t...
We review common extensions of particle-in-cell (PIC) schemes which account for strong field phenomena in laser-plasma interactions. After describing the physical processes of interest and their numerical implementation, we provide solutions for several associated methodological and algorithmic problems. We propose a modified event generator that precisely models the entire spectrum of incohere...
Particle-in-cell (PIC) simulation is the most important numerical tool in plasma physics. However, its long-term accuracy has not been established. To overcome this difficulty, we developed a canonical symplectic PIC method for the Vlasov–Maxwell system by discretising its canonical Poisson bracket. A fast local algorithm to solve the symplectic implicit time advance is discovered without root ...
