To understand in detail what happens with an imploding wire array
would require one to account for many different processes beginning
with the wire explosion and ending with the Rayleigh–Taylor
instabilities. Haines (1998) has performed a heuristic analysis of
the multiwire array implosion and suggested that the dynamics and
behavior of the wire array pinch be divided into four distinct phases.
These phases are as follows: the electrical explosion of an individual
wire (Phase 1), merging of the wire plasmas and the current shell
formation (Phase 2), running-in of the wire array (Phase 3), and the
stagnation of the pinch at the axis (Phase 4).
