now even though I searched the forums for keywords and came up with none exactly matching my case excuse me if this has been asked. Firstly is it possible to have a high pressure but low temperature self sustaining plasma? i do understand that temperature corresponds to the plasma particle average kinetic energy which must be high enough to form a "burning plasma" but can a plasma like that be possible with low temperatures but high pressures? Even though I guess high pressure and low temperature don't go together that well as increasing pressure usually increases temperature. Secondly I wonder what would happen or should I say how the plasma would react if it would be between two electrical fields (static ones) like from a high voltage dc source. Like between two spheres one bigger (outside) and one smaller inside. Now if one would be + and the other - then the electrons would attract to one and the ions to other but if both would be at the same polarity like ++ or -- what would happen then ? Would the plasma be confined between the two spheres by the electrical field ? As long as I remember plasma is a ionized gas made of charged particles negative electrons stripped from positive nucleus or ions.The net charge is neutral but it is effected by electrical and magnetical fields.
