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 ...

Re: Viable design?

... you considered the the Paschen Curve and determining the necessary parameters relating breakdown voltage, pressure, and gas fill? 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 ...

... as well. It is very easy to place a camera in front of the viewport and then shield the surrounding area. Can you elaborate on your shielding/safety precautions during fusion runs? Congrats on fusion and great effort so far. -Scott Moroch

Re: High Vacuum Engineering Design, Analysis, and Build of a Small-Scale Multipurpose System

... 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 ...

Re: Has anyone used the Spellman X3000 50V-30kV 400uA Rev E7 24Vdc

... current (with voltage) also determines the input power, is there a power rating that is best suited for "wall plug" use without compromising on safety?

It's another reason why I decided to spend my free time doing calculations and cad for my system, as well as ...

In regards to the calculations, so far I have completed the calculations for characterizing the pipeline conductance as well as effective ...
