I think you guys will like this one.


Everyone seems to like tori so much I figured I might
as well toss one of my own ideas on the heap.


Picture a textbook hollow metal torus and think of that
structure alone as the single "turn" of a "single turn torus".


Now to induce current in the wall/turn you need to get a current
flowing. One way I could envision would be to cut a single
narrow slot all around the outer wall of the torus at the widest
point. Now fill the gap we have created with a gas tight dielectric
seal to keep the vacuum of the hollow center of the torus intact.

Now along the top and bottom edges of the slot you extend
a pair of disk shaped flanges. Between the flanges you place
a ring of very large AC rated low voltage, high current capacitors.


To picture the whole structure think of a classic Holly Wood flying
saucer

except there is the smooth donut hole of the torus in the center of
the disk and the outer lip of the saucer flares apart at the top and
bottom into two large flattened cones until they are far enough apart
at the edges to hold he ring of large capacitors.


So what do you have when you get done making this thing? You have a
very low resistance torus (a single turn toroid coil that is an
inductance) that is paralleled with a large bank of capacitors.

Since the "turn" of the torus will have such a low resistance the
system will inherently have a high Q despite the low inductance of
toroid.

(I think so any how)

OK what to do now? You start exciting the current in the tank circuit
by applying a voltage at the resonant frequency of the tank.


In Electronics 101 we learn that the impedance of such an excited
parallel tank circuit will be very high indeed it will only be limited
to by ESR of the system (the parallel combination of the leakage
resistance of the caps the resistance of the toroid wall and the
resistance of the connecting flanges/plates). In other words the
resistance will be very low therefore the current induced in the tank
will be very high.


Now twice per cycle we have a very symmetric collapsing B field in the
middle of the torus. Notice there are no super-conducting magnets
required to get this big field and that it shouldn't take much of a
power supply to get the thing excited.


Now it looks like the primary loss mechanism will only be the
resistance of whatever sort of plasma load one decides to place in the
torus.


So you run the thing empty for a period of time while the current
builds up in the tank circuit and then right at the last second you
puff in a load of plasma.

So there you go, you have a very strong very symmetric B field
collapsing on whatever sort of plasma one wants.


Well what do you all think, any promise here? I know it's a little
rough yet.
