Does anyone know a good online resource or book, I have found a lot on Plasma, but I don't find much about interactions between plasmas and the details of Charged Double Layers, it always seems the mechanism for the charge separation is an unknown when I read about it. But my questions are really :
Can plasmas collide? Seems simple for a cold plasma if I think particle collisions. But is it simple for charged double layers with currents?
What happens when two charged double layers collide?
Do two plasma currents intersecting at 90 degree angle have a magnetic/electric field interaction?
It would seems treating it as a gas cloud is a no no, so particle collisions are not the way to think...but I really don't understand the interactions. Wiki sates that wave interactions are important. Makes me think of it as electromagnetic, like a giant pile of light. So they would attempt to self align to the magnetic field? What difference is their in interactions between a "cold" plasma or a "hot" one?
When I say interactions I mean one body of plasma interacting with a separate body of plasma, a collision.
EDIT
ok found this
Is it correct to say, pinches and double layers are the products of interacting plasmas of different densities and magnetic fields?Langmuir was among the first to note the separation of highly conducting plasma into charged-particle sheaths or cellular-like walls. This structure appears wherever samples with different densities, temperatures, or magnetic-field strengths come into contact.
In the EU theory it seems that the thought is all stars, and maybe all matter, is connected in a continuous electrical circuit, so the cold plasma of space is always pulled into alignment with the currents magnetic field forming the filament structure. Would there be a location that 2 currents of opposite or perpendicular directions exists, if it is one continuous current I think not. So my question being really about collisions between plasmas with currents of different directions, it may not be a natural occurrence...so not important...
^EDIT
Feel free to point out my ignorance, that what I'm looking for.
thanks.
