High
energy plasma: Exploding wires

When a __big
capacitor bank__ is
discharged through a fine wire, all the stored energy is immediately
transformed into heat energy. In detail the wire reaches temperatures
of several thousand Kelvin, which creates a local vaporization of the
metal. In the next phase there are many sparks between the still nonvaporized
metal particles. Because the ionization of the air molecules the resistance
in these "sparcgaps" varies. This nonlinear variation of the
wire- and air-resistance makes mathematical calculations very difficult
regarding these pulsed power discharge experiments. In this project
I want to find a theoretical explication for this type of "wire
explosion".

Many
parameters for instance the equivalent series resistant (ESR) and the
equivalent series inductivity (ESL) are important for the discharge
behavior of high energy storage capacitors. The calculation of such
parameters appeares to be simple when compared with the complex wire
resistance during the discharges.

So, the easiest way to understand these events is
by taking experimental measurements of the discharge current and voltage.
These measuremts are going to be the main aim during this project.

To be continued..........:-)
