Abstract: We present new solution methods for dynamics of counter charged beams in accelerators and plasma electrons dynamics in a trap with inverse magnetic mirrors and multipole magnetic walls. The models are based on the particle-in-cell method. These problems require extremely large computations and can be solved by the use of powerful supercomputers only. A modification of the euler-lagrangian decomposition is implemented in order to achieve full and balanced load of computational nodes in case of highly nonuniform particle distribution in space and time.

Keywords: particle-in-cell method, parallel algorithms, load balance, plasma physics, counter beams, particle accelerators.
