I realise that i did not answer many of the questions posed here, i will try to answer some of them.
In today's modern electronics, 80 nanoseconds is quite a long time. A complete cycle of this reactor is roughly 32 microseconds, it was designed to
run at a fairly low frequency., and if you need to stop it, you need to do it well within one cycle.
Initially this was done by a spark gap or gas filled tube, that would stop the main coil from reaching too high a voltage.
However, the plasma compression is done with current, so that means the greatest current is actually flowing when the voltage is at zero. Shorting the
coil at it's peak voltage will send a huge current pulse through the coil, and this of course may initiate another fusion reaction.
Let's talk about the Tokamak for a moment, because those peeps at CERN, ITER, JET and all the rest of them seem to think that you need a hundred
million degrees to achieve fusion.
So while they are throwing 12 billion a year into these projects, they are still getting nowhere.
They know this of course, but hey it's one big gravy train right?
If someone gave me that kind of money to play with, i would stall at getting real results, and spend more time on my jacht.
As it is, i have been quietly plodding away with my own meagre budget of about 5000 a year.
To start with, you don't need millions of degrees to get fusion, all you need is pressure. Lots of it.
And you don't need gigantic permanent magnets either, all you need is a time variant magnetic field, or as most of us call it, A.C.
Here is a tube of pure Deuterium at low pressure. It has been ionised using a high frequency field of about 10,000 volts.
I have placed 2 small magnets (about 10,000 gauss, taken from a senseo coffee machine) on each side of the tube, north poles inward. As you can see,
the plasma is compressed in the field and it gets very much brighter. Temperature is of course indicated by the emission of photons.
Here is a spectral graph of Deuterium, i built the analyser myself after watching some YooToob video's
After fusing, the D2 will become either normal Helium (He4) but there will also be Helium 3 and a stray neutron.
That is why neutron counters are quite important at this stage. I now have one that uses quantum PIN photodiodes, they can detect a single photon!
The trick is going to be if we can 'tune' the reactor to produce more of one element than the other.
Helium 3 while being slightly radioactive (it's missing a neutron remember) is also worth 20 times more than gold, as i have often pointed out. So our
'waste' from the reactor will actually be worth more than the D2 fuel.
There are many, many aspects and spinoffs that i have not yet talked about, but this may become one of those 'mega threads' that we used to
