As for electron motion, it may be helpful to consider an electron moving radially from the center and encountering the magnetic field. This electron will be turned anti-parallel to the current in the coil, reinforcing the magnetic field between it and the coil, canceling the field in the center. In ...

The accounting and measurement methods behind those figures is in dispute.

See my previous post this thread. run coolant not through holes in the tape but between layers of tape.

In a WB6/7 scale device I see fusion neutron production as a plasma diagnostic method. But the more other independent diagnostics you have data from, the better you can validate and calibrate the working theory. Running a plasma that doesn't produce neutrons can give a baseline for validating the ne...

"...forecast that we're going to be hitting $12 and $15 per gallon,” Gasoline prices get anywhere near that high and there are multiple alternatives ready to go fast track to replace oil. I don't believe prices will go that high, or stay so inflated if the market is allowed to respond with more liqu...

When you mention synthesizer and POPS together, I think Phase Locked Loop, adjusting POPS drive to match whatever the natural resonant resonant frequency is. Get the drive X hertz off in a high Q loosely coupled resonator and you get an amplitude modulated ringing at X hertz. I don't know how high t...

Isn't there a way to make the standoffs create their own magnetic field that will bend the coil's magnetic fields around them? This might decrease the chance of electrons hitting the standoff's (they might get stuck around them though). I believe so. To repost an idea from the magrid brainstorming ...

With the 'paranoid' security settings on my web browser (firefox with noscript plugin), the article intro didn't show up until I loosened permissions on that site. Afterwards, things appear to be working fine. I'm guessing excessive client side scripting without the recommended <noscript > block to ...

While we're discussing coil construction, I've been musing on something similar to a Bitter magnet, but wound from a ribbon conductor rather than stacked from stampings. A corrugated or porous insulation layer would pass the coolant running between the ribbon layers, rather than through holes in the...

If I understand what you are trying to suggest, you would want a magnet magnetized radially. Exactly. I have no idea how you would obtain magnets to that spec. Anybody? I have 2 ideas: - Piece together rings from bars with beveled ends. - Re-magnetize a ring with the orientation you want by sandwic...

Re: RF sampling of the plasma
Depending on the bandwidth of interest I might be inclined to feed the probe signal into a video capture card in a computer with a custom driver.

Re: driving oscillations
Hitting any resonant system with a pulse, such as the startup on WB-6/7, is going to make it ring.

My impression is that WB-1 used magnets where the poles were opposite flat faces. A variant of WB-1 that might be interesting is if you could get, or make, ring magnets where one pole is the outer face, the other pole the inner face. Space the magnets apart a little like WB-6. I don't expect better ...

Unless experiment shows otherwise, injection of low energy neutrals from the inner face of the magrid should work fine. I.e. a puff of gas, very distinct from high energy neutral beam such as sometimes used to heat a tokomak. For best time response, injector valves squeezed in the magrid may help.
