A Model Based on Lumped Parameters for Filippov-type Plasma Focus Devices

摘要

A model based on the Lumped Parameters has been presented for the description of behaviour of the Filippov-type Plasma Focus devices. Some results of this model for "Dena" Filippov-type Plasma Focus device (90 kJ, 25 kV, 288 μF) with Ar as working gas and different values of gas sweeping efficiency factor (f_m) and current efficiency factor (f_i) for 16 kV discharge voltage and different initial pressures have been compared with experimental results. It seems that using f_i = 0.7 and f_m = 0.1 gives the best agreement between experimental and calculated results.
