What is the structure of plasma?

Based on the given topics, we limit ourselves to plasma control in physics, so no blood plasma, etc. medicine or plasmas of biology.

And then we have to figure out what a plasma is. Salopp said it is an electrically conductive gas. If we become more accurate, then it is a gas whose average free path length of charged particles is higher than that of the unloaded particles.

Thus we divide a plasma into a proportion of plasma gas and a background or neutral gas.

Plasmen are now in many places, for example the gas discharge of a fluorescent lamp (“neon tube”, “spar lamp”, …) runs in the plasma. Or in the sky as a polar light. The plasma itself would not differ from a gas for us, only the environmental conditions are “unsund” for us: A gas discharge takes place in an E field, depending on the strength, it would not even tingle (“plasma lamp”, so’n fashionable physics thing) or endanger or kill us. (L phosphor lamp). At the heights where polar light shines, we would not perceive it as a gas, but as an “air empty” (and “unsunding” would then be the electrons at the cosmic speed of the sun wind, which produce the polar light).

That’s one end of the scale.

It becomes more stapler at the other end of the scale, with not only “hot” (but also not “healthy”, for example in the plasma cutter or in the flash) but also dense plasmas.

In the tokamak of a nuclear fusion reactor or in the sun, we find the hot, dense plasma, which, however, alone because of the energy, does not allow us to approach and would not feel differently, like a very hot fire. The processes in the plasma are “real” (sometimes the Pictures looking at the DLR) and only the gravitation on the sun cover would crush us. Alone, until then, we wouldn’t come because the sheer energy would have broken us into all parts before.

Somehow, the question can ultimately not be answered, but can only be approached here by these descriptions. Please also Wikipedia read more!
