Re: Making my own bell jar reactor

<t>It all depends on the quantity of lead in the glass.<br/> <br/> If you are running at less than 30KV then the X-Ray intensity will be cut in half for every 0.02mm of lead equivalent. 50% lead glass would block half of the radiation with 0.04mm. 25% lead would be 0.08mm and so on.<br/> <br/> For y...

Re: Bell Jar Viable for Fusion?

<t>Yes,<br/> <br/> The potential for an implosion exists because of the pressure differential across the bell jar. 15psi times the surface area of a decent sized bell jar turns out to be an awful lot of stored energy. The hazard exists because glass breaks suddenly into fragments instead of bending ...

Re: Bell Jar Viable for Fusion?

<t>Can you do fusion in a glass vessel? Sure, if you wish. It's been done before.<br/> <br/> The reason it's not popular among the old hands is because it adds danger, cost and complexity.<br/> <br/> Danger from X-rays and potential implosion.<br/> Complexity from extra shielding both inside to prot...

Re: Transformer

<t>Sorry Mario, <br/> <br/> I wasn't trying to give you a hard time. We've had a lot of people come and go over the years and one thing that I've noticed is that the people who actually complete something around here are the ones that do the search on their own. Maybe it's something about personalit...

Re: Transformer

<t>I appreciate you correcting your name, Thank you. Please add your last name too when you have a chance.<br/> <br/> As far as transformers go, it sounds promising so far. I don't know enough about that model to tell though.<br/> <br/> Search for "Neon Sign Transformer" and you'll find a few hundre...

Re: NYTimes Gets Two Out Of Three

<t>Ok, let's take a closer look at that.<br/> <br/> Here's were I'm starting out.<br/> Us: 1E7 Neutrons/s Peak, sustained. <br/> JET: 5E16 Neutrons per pulse. Repeatable once every 45 minutes.<br/> <br/> Neither of these systems is really capable of always on performance so I can't factor in failure...

Re: NIF.. "new hurdles" reported...

<t>I seem to recall reading that there have already been enough lasing crystal failures at NIF that a couple of the engineers have actually begun using the coffee table sized blocks of doped glass for, well... coffee tables. I don't know what that would run on ebay, but I want one.<br/> <br/> The re...

Re: Rotating Ions to create both high density and high velocity

<t>The particles in fusor can be moving at millions of meters per second. It's not practical to physically spin an electrode that fast.<br/> <br/> Google Cyclotron. That can create the kind of circulation that you seem to be looking for. In some configurations it can even do some fusion. I believe t...
