Zpinch works by running a strong current through the plasma which sets up a field that tends to confine the plasma, so if the current is switched on rapidly the resulting temperature increase and B field increase tends to compress the plasma channel rapidly, at least this is how I understand the concept in it's basic form.
I tried googling but did not find any related materials, has anyone ever tried to run a tokamak reactor in such a way?
In theory instead of using direct electrodes like in the Z pinch the tokamak creates a plasma current as a secondary from a drive primary transformer, so what would happen if this primary current was a pulsed square wave?
Assuming of course that the plasma stays in the plasma state between pulses.On a more general note, is it possible in theory to have a net energy gain from a pulsed fusion device , even such that the plasma cools off between each pulse?
the confinement time is very small compared to a tokamak burn but on the other hand since confinement is not necessary one could use much higher pressures of DT gas which should result in a higher fusion rate.
I guess the simple requirement is to have enough energy out from each pulse to account for energy spent on each pulse + net energy gain.
