Alright, I've been looking around for an opinion on this for awhile: Suppose you have a tube of deuterium whose radius is much much less then the length. You use a high voltage/large current to ionize this Deuterium. In a similar configuration to the Z-Pinch device a magnetic field is created. Here's what I wish to do, but have no idea if It would work. Let's assume that I hook a high voltage device up to a function generator and modulate the frequency of the AC current, which then creates and magnetic field, which then will be alternated at the resonant frequency of the tube, causing the Plasma to move at the resonant freqency, which would then confine the gas into antinodes just like if a speaker would if it was put at the beginning of the tube. The only thing that is different is that I would have to account for the tube being closed-closed. Confined Plasma could then be confined to the center by using a pulse type ac current, which then could be bomarded by a laser blah blah. Decent Idea? Has anyone done this? Is it feasible? Thanks!
