Investigation of a 5 kJ conical Z-pinch discharge
A conical 5 kJ Z-pinch experiment with 35 μs discharge time was constructed and operated.
Preliminary results showed that the total circuit parameters are 287 nH inductance
and 13 mΩ total resistance.
The cone plasma inductance has its maximum value at the pinch. It has been determined that
the pinching time is inversely proportional to the deposited energy. Moreover, a
calculated delay time of about 2.1 μs is required for the pinch to occur and the
calculated sheath velocity ranges between 1 and 11.5 cm/μs. Erosion of the pin
electrode could potentially explain the difference between the mass of helium gas inside
the cone and the calculated swept mass. The main product of the ionization process is a
singly-ionized helium atom
