The paper reports on the results of a 3-D modelling of ion motion within the plasma focus (PF) pinch column, which is treated as a filamentary, non-stationary system. Besides magnetic fields, also the induced electrical fields as well as the ion-ion and ion-electron collisions have been included in the equations of ion (deuteron) motion. The results obtained show that the filamentary structure influences the 3-D ion trajectories and 2-D angular distribution of ions. It has been confirmed that 3-D flower-like filaments can explain some important characteristics of the ion emission from PF discharges.
