Re: micro ac tukomak
- The plasma is inductivly linked to a coil carrying RF. The plasma
itself is equivilent to a loop of wire which has resistance. The
circuit is therfore a transformer with the one turn and series
resistor being the plasma. So the plasma is in series. The primary
of the transformer is the coil of the tuned circuit.

- i wasnt doubting your device, i was disputing what ever her name was, description of fusion reaction.sorry you thought it was about you. i hope that you suceed with your device.jim

It is not as simple as that and the tube will only give power at 20
KW for 5 hours. I suggest you read Edward Tellers book on the
hydrogen bomb. You may not be able to buy it easily as it is probably
classified. I found it in the library at aldermaston nuke factory
where I once worked as a junior physicist.
