Re: Baratron
<t>The only thing that I would mention is the heated Baratrons take hours to warm up and fully stabilize. (4 hours seems to be the norm) The unheated ones are fully ready to go in about 15 minutes. So that depends a lot on how you run your fusor. If you want to have a group come in, power the thing ...

Re: Bell Jar Viable for Fusion?
<t>Hello Jeff,<br/> <br/> I thought I would mention some things we noticed from our attempts at the University of Utah, perhaps it can help you make a decision. You are right that we did get a small amount of fusion from the university's bell jar fusor. However, the bell jar does limit you in a numb...

The original listing for those turbos sold out yesterday, however the seller re-listed ten more.

Re: Inaccurate vacuum?
<t>The simplest way to do a rough calibration on these types of gauges is to hook it up to something like a diffusion pump or anything similar which will pump below the measuring capability of the gauge. Once you know the pressure is below what your gauge can distinguish, just adjust the reading unt...

Re: Fusion or Explosion
<t>Steven, the biggest reason the sun does not run into that problem is that fusion does not occur on the outer layers of the sun. As per wikipedia:<br/> <br/> "The core is the only location in the Sun that produces an appreciable amount of heat through fusion; inside 24% of the Sun's radius, 99% of...

Re: Archived - University of Utah's new demo fusor - we have fusion!
Awesome, thank you very much Richard. I would like to ask if it is ok that Adam Beehler's name be added as well, as it technically is his fusor, and he was an equal on this project with me.
Thanks again, I am really excited and honored to be part of the club now.

Archived - University of Utah's new demo fusor - we have fusion!
<t>Well, I think we finally got it...<br/> <br/> Over the past months, we have made a few changes to our fusor at the U of U. Following the recommendations here on the forum, we made a new inner grid which is much more transparent to incoming ions. At first the grid was silver-soldered together, whi...

Re: What type of flange?
<t>It looks very similar to an ASA style flange, although there is a chance it could be no standard flange at all. That diffusion pump comes out of an old Veeco leak detector (an MS-9 if I remember correctly) and I know some of those old leak detectors have their own odd choices in flanges and fitti...

Re: Fluorinert Alternative?
<r>You could always try reclaimed fluorinert.
