This workdiscusses the values of the CS inductance extracted from severaldischarges of the PACO (Plasma Auto COnfinado) plasma focus,installed in the National University of the Center of Buenos Aires ?Argentina (2kJ total energy, capacitor bank of 4μF charged to 31kVand a maximum current of 250kA).The temporal variation of the current sheet (CS)inductance in a plasma focus device can be calculated using thecurrent derivative and the voltage signal acquired on the anodeelectrode, which are very common measurements in this type of device.The value of that inductance contains important information about thedischarge performed including the CS lift-off from the insulator,voltage between the pinch extremes, maximum energy of the x-ray,energy delivered to the pinch and information about the actuatingfusion mechanisms if the filling pressure is deuterium.
