hanelyp, I dreamed up the same thing while at EMC2. A "watch spring" magnet winding would eliminate the ungraceful steps in winding at the end of each layer, unavoidable when using wire or tubing. It should cool very effectively. The problem with this configuraton is making it conform to a circular ...

Tony, For little machines on the pattern of WB7, using copper coils, I think I^2R in the copper is going to be the overwhelming source of heat in the coils. That's based on my experience with WB2 and WB3 running on a pickup truck worth of lead acid batteries to power the magnets, and some preliminar...

Solo, The pie-shaped conductor idea stems mainly from the need to achieve a uniform field around the conductor using what must, due to the cooling needs, be fairly large conductors. Using tubing or square channels to build up a round cross section magnet won't fill the case smoothly. But my first id...

"Read More" is dead as a doornail for me, but "Go To Archive" was working. Since there is only this one article in the archive, that was easy enough!

Nice article, Tony!

I get to the page, but "Read More" doesn't seem to do anything. Do I need to register, or do I simply have my security torqued too high?

Well, then, in light of the above and in realization of the fact I'd never get around to contacting a patent attorney, and my wife would faint if she heard the cost, here's the idea. The problem is how to pack the most copper into a round cross-section magnet, and still be able to put cooling channe...

Tombo, I've used both a helium leak checker and a residual gas analyzer. I conclude helium leak checkers are a waste of time. The RGA will do that job perfectly well, but it will also distinguish between a real leak and various types of outgassing. Once the actual leaks are sealed up (the RGA will s...

Actually, I'm not so much trying to be proprietary ... its just that I've had so many neat ideas over the years that could have been patented and have made a mint for someone else. Every place I've worked, if the CEO had a bright idea, it was patented. If I had a good idea it was considered trivial....

Dr. Mike, WB4 was water cooled, as were the MPG machines. WB4 used custom-made square copper conductors (about 1/2 inch on a side) with about a 1/4" water channel down the middle. This packed the conductors tightly, but unfortunately was only suitable for square cross-section coils. I was around whe...

The electrons won't just fly off ... the emitters and walls are at about the same potential, and the magrid is positively charged to 10 kV or more. They're strongly attracted to it, and want nothing to do with the walls. They keep moving because of the high kinetic energy imparted by the grid (they'...

It is hard to say the gage without a good scale ... I might have guessed 8 AWG. My experience with WB2 and WB3, made with 12 AWG magnet wire run at a couple of hundred amps, was that it got hot in a hurry. Depending on test duration, you might only have a few seconds to a minute before the copper go...

All, the http://emc2fusion.org/ website has a new picture up, of a helium plasma in WB7! :) I always studiously avoided using He, as it would have been indistinguishable from D2 on the residual gas analyzer. It will doubly-ionize, and might have some useful distinguishing spectral characteristics th...

I recall having the "large" chamber built. When we visited the plant, and saw our 12-ft long 6-ft diameter chamber out on the floor, I realised the hemispherical end cap of another chamber they were building could be placed over ours with room for several more like it! They can supposedly build them...

Torulf2, I assure you, your English is far better than my Greek. Without your courage to communicate, we would not be treated to your great graphics and interesting insights. I met Dr. Koloc when he visited the lab in the late 90's, at which time he was interested in the spheromak/plasmak as a model...

MSimon, I have a couple of ceramic speaker magnets out in the garage that ought to hit about that. We also hit levels like that fairly easily in PXL-1, while injecting microwaves from a microwave oven tube. A microwave oven frequency of 2.45 GHz will produce electron cyclotron resonance at 875 gauss...
