Re: Lockheed Fusion?

I think it's rather telling that the paper on plasma physics was submitted to the aero/astro department. I doubt it would have passed muster with anyone in course 22.

Re: NEUTRONS!!!

Jaime, PM me and I'll walk you through the math. I'm in agreement with Richard that this sounds a bit off, but I'll reserve judgement for the elders of .net.

Re: Demo Fusor Soft X-Ray Detection

To be fair, there is free-free brem happening in the plasma, but I'll still side with Chris in that this thesis needs tweaking. If you're really interested in plasma density, take a look at the wiki article on langmuir probes.

Re: A quick reply...

Just because it's available does not imply safety or legality. Further, that ampoule is in fact safer than your balloon, as it's not a big, leaky static-y bag poised to burn violently at the drop of a hat. Further, the USPS has some choice words on mailing gases: http://pe.usps.com/text/pub52/pub52c...

Re: A quick reply...

1) That's not an inconsiderable amount of D2, and it definitely falls afoul of hazmat shipping regulations. If you want D2, buy your own D2O and figure out the rest. Further, it's impolite to repeatedly ask the community to do something blatantly illegal. 2)In order for your idea to be taken remotel...

Re: Soft x-ray induced fusion is the way to go!

The Teller-Ulam design relies on soft x-ray compression to achieve the enormous pressure and temperature required for ignition. There's an enormous difference between shooting a few stray x-rays at a balloon of D2 and compressing something to the point of thermonuclear fusion using photon pressure. ...

Re: Thermocouple gauge

Please read the forum archives. There is plenty of good info on thermocouple gauges. Others have used similar units, and they seem to work sufficiently. As for the baffle, I would imagine it's there to keep out diffusion pump oil and other debris.

Re: My First Run of Diff Pump

Jason, where are you in the greater Seattle area? I have a Welch 1402 in Renton that I can lend you. I'm in Boston until Christmas, but if you can wait that long, I can get you something capable of 10 microns.

Re: Minimum Voltage for a Demo Fusor

MOTs are a terrible idea. Please, for your own safety and the financial wellbeing of your life-insurance company, use a NST. While you certain can employ MOTs to power a fusor (using several chained together with a multiplier on the output), they are exceptionally dangerous.

Re: Fusor construction efforts

The scenario I presented is extreme, and I made that clear in the post, but I feel it highlights the danger of the situation if it's handled poorly. Even if the air contamination is 2% of the concentration that I presented, it's still enough to cause "observable teratogenic effects [in rats] after 2...
