Re: Helium-3 Fusor Thread

... your device, is legality. Assuming you aren't running the bare minimum and are running over 100kv, there is a real health hazard from a radiation safety standpoint. This might be enough to raise an eyebrow from the local governments or (if you aren't in an agreement state) the NRC. Normally fusor ...

Reactor Plasma Imaging

... missing one of the two electrodes. To turn the new probe into a usable tool we designed, tested, and built a high impedance voltage divider and safety network with a ratio of 100/1 and an input impedance of 20 megaohms. The high impedance was necessary to avoid “loading down” the plasma. To ...

Re: Bonding Tungsten and/or Iridium?

... using the same transformer. Box contains transformer along with a momentary DPDT toggle switch that switches the primary and a fuse holder for safety. Timing is by hand, in typical messy-and-simple Krase Laboratories style. Hold-pressure is also by hand -- for a while I thought this thing wasn't ...

Re: FAQ - Joining metals - A critical fusor construction element

... two "sticks" of silver brazing rod (it may be rolled into coils instead) which will run you roughly 30 to 50 USD if I remember correctly. Harris Safety-Silv is probably good. You probably want to avoid cadmium, IMO. - Silver soldering works great on stainless, brass, copper, and steel -- totally ...

Re: Seeking Advice

... Read the FAQs! I know Mr. Hull will appreciate this one. The FAQs include all the info you need to build and operate a Fusor. They also talk about safety, which is something you should pay a lot of attention to if this is you're first interaction with high voltage and radiation (fusion was my first ...

... to go out and buy all the parts willy nilly and I'm looking for advice on A: Saving as much money as I can, And B: How to approach fusion with safety. I've researched farnsworth fusors and got the gist of it, But I still have a limited understanding. Any information would be appriciated. Cheers ...

Note also the safety considerations - arcing through deuterium can create explosive conditions if there is any air remaining in the chamber. Have you considered the ...

... speed still, and as such, a backing pump has been selected with a displacement of 2.83 L/s, much more than is required for this system with a good safety margin. This should allow me to still attain 600 L/s at the pump inlet, while having additional overhead. Because the actual gas load will be ...
