New Copper Coil Polywell on the Scene

25 12 2009

Researchers at the University of Sydney have made a small Polywell device which looks like this:

Powerpoint slides of their research here.

Notice there is no metal exterior on the magrid. As far as I understand… instead of using a magrid with a shell at positive potential (like the WB6 does), they are shooting in electrons with kinetic energy from an electron gun.

This seems like a feasible way to build a copper coil polywell. If the researchers are willing and able to share the details of the experiment, I would explore replicating the device and results. It looks manageable:

Cute! I’ve been wanting to see the amateur fusion community work with WB devices of this scale. This one is about half the size of WB-2.

It is a nice first step for a low-power device.

Looks like a nice affordable way of building a low voltage polywell device. Arcing would be a problem at higher voltages needed for fusion, but lesser voltage would be enough to study plasma dynamics. I note the spacing between coils is much less than WB-6, which suggests losses at those cusps would be huge.

When you look at the coil spacing, you can ignore the teflon magrid (I think). So the applicable distance is between the coils themselves.

Additive Manufacturing

I’m an additive manufacturing specialist and it seems that the Magrid chassis could be manufactured in titanium using a Powder Bed Fabrication system that opperates under vacuum.

Are you interested ?

Are you speaking of the arcam-ab process?

the square plastic coil casing on that polywell will cause alot of electron losses.

What voltages must be used to attain fusion in a polywell. Also, where can a Magrid be purchased?
