| Abstract |
We present our parallel 3D3V particle-in-cell code for the numerical simulations of ultrarelativistic charged beams in supercolliders. In the algorithm we employ the three-dimensional set of Maxwell equations and the Vlasov-Liouville equation for the distribution function of beam particles in 6-dimensional phase space. The code allows performing numerical experiments with an arbitrary density distribution, beam crossing angle and relative offset. From the mathematical point of view the main problem of the three-dimensional modeling is the presence of the high relativistic factor values (the field gradients are high), the convergence conditions for PIC method and the necessary number of particles in 3D cell. Thus the parallel algorithm is based on the mixed Euler-Lagrangian decomposition in order to achieve good load balancing, and demonstrates the high scalability. With the advances of the code it will be possible to apply it for one-passage beam-beam simulations in linear colliders with supercritical parameters. We present the results of numerical simulations of colliding beams using dummy parameters and parameters close to the ones of the newest ILC project.
