 Plasma Science Report, 1995 (Contents and Overview)
The plasma medium is inherently nonlinear because the charged particles composing the plasma interact collectively with the electromagnetic fields produced self-consistently by the charge density and currents associated with the plasma particles.
The intellectual challenge in plasma physics is to develop the principles for understanding the complex macroscopic behavior of plasmas, given the known principles that govern their microscopic behavior.
Examples of applications of nonneutral plasmas are electron beams and plasmas for the generation of electromagnetic waves, pure ion plasmas in traps for atomic clock applications, advanced concepts for particle accelerators, and the confinement of antimatter such as positrons and antiprotons.

Plasmas have special electro-magnetic properties compared to a normal, neutral gas due to the fact that the electrons and ions are not bound together.
The important properties of a plasma are that it is subject to electric and magnetic forces and is a high energy state of matter.
The problem is that a plasma, like a gas has a tendency to spread out when there is a large pressure difference, and unlike a gas the high pressure plasma can not be confined simply by a metal wall because of the high temperature of the plasma (around one hundred million degrees C).
