I've been reading some about the ITER project, tokamaks, and other approaches to plasma containment. Why can't ion trapping approaches such as an orbitrap be used for fusion plasma containment?
Does a plasma have a net charge?Clearly confinement alone is insufficient. You also need temperature on the order of 108K to generate high energy collisions (as you mention), plasma of high enough density that collisions occur frequently for a long enough time to have a good probability of some of them resulting in fusion. However I still don't understand why electrostatic fields wouldn't be very useful in containing the plasma at a decent density for long enough for fusion to commence. Clearly heating would need to be accomplished by some other means (not particularly relevant to my question).
