The distribution of argon ion beam emitted from a small plasma focus device (PFD) with four different anode tips i.e., cylindrical with a flat top, cylindrical with a hollow top, cone with a flat top, and cone with a hollow top is studied at various working pressures. The angular distribution of ions is significantly reduced at angles higher than +/- 11 degrees and the maximum ion emission is between 0 and 11. The maximum ion flux of about 5.57 x 10(12) ions/steradian is obtained with cylindrical-flat anode tip that increases to 9.82 x 10(12) ions/steradian per shot for cone-flat anode tip.
