The generation of energy-efficient parallel scientific codes became very important in the time of carbon footprint reduction. In this paper, we briefly present our latest particle-in-cell code with the results of a numerical simulation of plasma dyna

The problem of the evolution of an ion beam in a fully ionized plasma is investigated using computer simulation. The 2D-3V axisymmetric composite numerical model is based on the particle-in-cell (PIC) method for both the ion component of the backgrou

The hybrid models are widely used to model plasma processes as they require less computational costs comparing to kinetic ones. The essential differences in space-time scales of the motion of ions and electrons lead to instabilities which are as of p

We present a new algorithm for numerical simulation of beam dynamics in the modern supercolliders, where the beams move with ultrarelativistic speeds and collide with crossing angle (~20 mrad). In case of critical charge densities the colliding beams
