Plasma question

[coolio]

I'm a total noob here, and I was working on something and came across a problem:-(. I think that I might have a solution:D, but I'm not sure if it would work. Anyways, my question is, could you bring plasma down to a temperature of about 1 mK using a laser (they've done it before) and have it stay that way?

Thanks

Not really no.

 

The problem is the temperature dissipates, so you need to thermally isolate the plasma as well as stopping any recombination.

 

Fusion reactors such as the JET attempt to do this and can sustain it for a little while but there is also was perturbation that results in a collapse of the plasma...
