What the gentleman is pointing out is that to get a significant magnetic field (fairly necessary for a Polywell) you need an high number of "amp-turns". With copper tubing, you will have fewer turns than with thin copper wire. Therefore, you will need to feed in more amps. But the copper tubings will allow higher amperage. The benefit (in my opinion, but I've never built one so it is just an opinion) is that the tubing will allow a MUCH easier job of cooling, expecially cryo-cooling, so the ability to cram more amps in becomes easier still.ladajo wrote:you need to get it dipped and baked. You could try to wrap it by hand, but you will end up with no turns. No turns means you would have to slam it with current to get any kind of field.
Various writings (no, I can't point one out but they are there) have indicated that the MPG design of coil manufacture would be very amenable to this kind of MaGrid design.
I am not sure what his problem with hand wrapping tubing is. If you go wire, I would agree with him. But tubing should be reasonably simple to hand wrap. Again, an opinion.
My suspicion is that the hardest part will be getting a nice smooth "can" for the coils that will allow a high MaGrid charge without arcing.
Thoughts anyone?
