Home fusion project

Having failed to even ionise low pressure hydrogen using an induction coil
with an interruptor I'm building an RF oscillator out of the same
components. It is going to have a small transmitting mullard valve (used but
tested working) as the active element, a 11 turn coil, a split capacitor of
5nF and a 2400 volt rail with a current of 50mA in the anode circuit.

I'm using a grid bias of -690 volts with a 10meg pot to adjust the bias to
alter the current.

The resonant frequency should be about 1MHz, the Q about 2000.

The current in the tank circuit will be about 100 amps and so a current
sheet of 1000 ampere-turns facing the hydrogen tube and with 200 volts
around the hydrogen tube, this should be enough to ionise it and so a
current of 1000 amps will flow in the hydrogen plasma.

This will put an inward force on the ionised gas thus making a stable line
of ionisation down the axis of the coil in the hydrogen gas.

Very close to the axis the pressure on the ions rises to hundreds of
atmospheres and the ion temperature rises to millions of degress K.

We should then initiate fusion here and the coupling of the ions by
induction will put emf in the coil and thus maintain oscillations when the
exciter is turned off.

And we will be able to draw power.

I think I need a regulator to prevent runaway fusion to happen, a shunt
regulator must be used but a valve will not do. I can only think of a
saturable reactor for this, but I don't have one.

If it gets too hot I take out the hydrogen tube.

That is the theory.

Any comments from the professionals?
