The plasma focus filaments are investigated in the simple plasma model with the London current. The filament solutions depend on two main parameters - on the speed of filament motion (supersonic, subsonic and zero) and the filament radius which is less or more than the London penetration depth. The corrugation instability of rarefaction shock waves is studied in detail as the mechanism of the plasma focus filament generation.
