For the plasma focus device AECS PF-2 operated in Ar and INTI PF in Ne, model parameters of mass and current in the axial phase of plasma focus were found by matching the measured and calculated current waveforms over a range of pressures. The results show a value of f(m) = 0.05 +/- A 0.01 over 0.2-1.2 Torr in Ar; and f(m) = 0.04 +/- A 0.01 over 0.7-4.1 Torr in Neon. The value of f(c) = 0.7 was fitted for all cases. Combining these results with those published for several other small machines it would appear that, where measured current waveforms are not available for example in designing new machines, a good compromise would be to take a guideline value of f(m) = 0.05 and f(c) = 0.7 for both Argon and Neon.
