Fusor Forums

Interesting thoughts Richard... Having read these past months about the economics of electricity generation I also agree that the challenge is not only in getting a Fusion reactor that can generate electricity reliable (a huge challenge in itself) but getting it to produce electricity in an ever mor...

Back with some updates, the XRT is basically done. I opened up the supply and pulled the XRT, removing the diodes, ballast and measuring resistors. Initially there was hope, as with 1V input I was measuring 400V between both secondary windings. However, as I increased the input voltage I noticed inp...

Will test accordingly when I fix my supply (or get a new one). Perhaps there is a better material to join the pipe to the flange than epoxy, however it must be non conductive so as to not short the main electrode with the flange. This is just one take on how to make a feedthrough, there's also Liam ...

Many have been recently building smaller chambers, their own feedthroughs, cheaper neutron detectors, D2 from PEM cells, etc., to help in keeping costs down to the fusor builder. Here is my take on how to make a cheap feedthrough that can take more than 50kV, it also looks like a lightsaber. It cons...

Back with updates from the past few weeks. I learned that it does take time to make your own power supply. Rich was right in that baking at 100ºC won't damage components, however if anyone does this with their own supply, make sure your wires can take the temperature. I left it all in a bucket and m...

One possible upgrade to the fusor is a “virtual” cathode, as to fix the issue with thermionic emissions (which are a waste of input energy). EMC2 tried to achieve that with their pollywell. According to a paper by Robert Bussard with a 10kV well depth (out of a 12.5kV drive) they got 2E5 n/s out of ...

Not very familiar with electronics as advanced as what you want, but perhaps this thread can give you some ideas viewtopic.php?f=11&t=13134

Good luck

Mark I noticed in your video that you have a "The Nucleus" counter. I also happen to have one and a Nuclear Chicago BF3 tube. IMG_0009.jpg Since it has adjustable voltage, could I set it up at 750V and start counting nuetrons? I don't have any specs on my tube (and I searched without success) but I ...

Maybe a system such as this one viewtopic.php?f=6&t=9435&hilit=generator will allow for better results?

Got the supply all wired up and ready to be filled with oil: IMG_0055.jpg Thankfully I have a friend who will help me with filling the tank with oil. He has years of experience in the utility transformer business and has equipment to correctly fill the tank. His idea is to bake the supply (without t...
