3D-PIC simulation of the electron beam interaction with modulated density plasma

In this paper, the three-dimensional(3D3V) numerical model is developed for the simulation of enhanced electromagnetic emission due to the beam injection into the modulated density plasma. The proposed model is fully kinetic and based on Particle-In-Cell method. The results of numerical experiments for different beam and plasma parameters are presented. Comparison of the radiation efficiency for the flat plasma layer and circle plasma column with different plasma density modulation amplitude are obtained. Numerical experiments have been performed using computer systems with parallel architecture.
