Re: [Requist] Looking for vacuum equipment (NL)

There are some Vacuum pumps available cheap at UC Davis as of 10-15-2018. Have to pick them up though. See the attached brochure.
I'll post this in the trading post as well.

Re: Boosting Power with Low Voltage

- Noah, I suppose that in order to do something like this you would have to float the low voltage. There may be a number of other things necessary as well. Think vacuum diode triode etc. It's just a thought. I have other things that I will do with the supply before trying this. Ouch Chris, I wouldn'...

Boosting Power with Low Voltage

Has anyone tried adding DC power to the fusor in a low voltage range to boost power in the discharge, and then supplying only a small amount of power with the high voltage? No particular reason except that I know that the fusion output is strongly dependant on the power levels in the plasma and wond...

They do not have the same velocities. You can find references to this in a search.

Re: Cheap, 3d-printed inner grids

<t>Honest question. If it works as a grid, does it really have to be strong and durable? I don't recall any information about how strong except if its too thin, it's probably too easy to melt. <br/> <br/> Other items work pretty well without much strength. A coleman lantern mantle for instance. And ...

Re: Anyone Build a Neutral Beam Gun

If it weren't for the acceleration/containment problems of neutrals, it would seem from a novice point of view that neutrals should fuse with lower energy input because of reduced Coulomb repulsion enabling a closer approach of the atoms before a steep rise in repulsion.

Anyone Build a Neutral Beam Gun

Has anyone done any work with making a neutral beam gun (D of course and low total power) for use in your fusor or other device? I know it would be quite a bit more involved than an ion beam.

Did you have any success?

Re: A new topology for building a low-cost DIY HV power supply ... 30kV/80W for $25.

Wow Chris,

Thanks for posting. Beautiful work. I can't wait for the rest of your project details. It's very inspiring. It looks like this design could be made ultra compact.

Re: Tuning reaction with de Broglie frequency

<t>Chris,<br/> <br/> I use frequency instead of wavelength because it fits with the concept of resonance in my mind.<br/> <br/> Obviously when two D's approach they can have only one rate of approach, however in the lab frame of reference, if they have different speeds, they have different momenta a...

Tuning reaction with de Broglie frequency

<t>I have an experiment to be carried out in a fusor which I would like to suggest because I will probably never be able to do it. Produce dead horse, begin beating. It is based on this idea...<br/> <br/> If you input these two:<br/> resonance 1<br/> resonance 2<br/> <br/> Your output will be these ...
