Abstract :
Particle-in-cell codes for intense beam dynamics studies with space charge include parameters defined by the user: number of modelled particles, number of grid points and integration step. The combination of these parameters has to provide the most accurate calculation of beam dynamics for a reasonable computing time. Analytical solutions for intense beam dynamics problems with space charge allow comparable runs of codes with controlled accuracy of calculations. In present paper test problems using the PIC code BEAMPATH are given
