Alternative magnetic shielding for PMTs.

<t>Hi,<br/> <br/> I'm just starting to wrap up my PMT/BC-720 detector, but I don't have any mu metal on hand.<br/> <br/> I've thought about putting the tube inside of a standard steel paint can. I would center the tube down the axis of the can, so there would be at about 1.5" inches of space between...

My Photos from the HEAS gathering 2006 (super late)

I'm slow to resize, crop, and post, but here we go. Looking over these pics again reminds me of what a good time Ashley and I had.

Re: Archived - Science Fair Demo Fusor

<t>Matt,<br/> <br/> I'm glad to see students are still representing the IEC at science fairs. As far as I know, me and Micheal Lei kicked this off in 2002, with the ISEF and JSHS competitions.<br/> <br/> It looks like you're off to a great start. No doubt soon you will learn what a bitch high vacuum...

Re: Toroid fusor

<t>Hi Other Adam,<br/> <br/> It's funny you should mention this shape of grid; I actually brought a small, roughly made toroidal grid to the recent HEAS meet. I just whipped it up to show to a few folks to see what they thought about the idea.<br/> <br/> The grids are easy enough to make. First I ma...

Light, Magnetic, and Electrostatic Shielding of the PMT Enclosure.

<t>I'm just getting ready to deposit my scintillator in an enclosure, and I was wondering if anyone had any tips on shielding it properly. <br/> <br/> For the electrostatic I have the PMT wrapped in aluminum foil, which is grounded to the steel enclosure (which in turn is earth grounded).<br/> I don...

Re: Anomalous event

<t>Wow. Congrats on the interesting event, Jon! I think everyone else had already said what I might say about it, except I do plan to run more than one neutron counter at a time. I have enough materials on hand to make 3 scintillation detectors (2 BC-720's and 1 BC-400). This seems advisable, becaus...

Re: FAQ - Fusion - what is it? How do we know we are doing it?

<t>Nice FAQ here, because these questions do keep coming up. It's amazing how many people who are engineers and scientists who make claims like (and I do quote) "You need several MeV to do any fusion at all." and "This machine is too small to do fusion." I made a point from then on to always carry a...

Re: With a Bigger Hammer...

<t>The nuclear department at my college has a "fusion research facility", but all the research is done on paper, mathematics and calculations.<br/> <br/> Up until 1996 we had a research reactor. It was a 5 MW job, heavy water moderated, and was considered to be the best suited reactor in the world f...

Re: 30 seconds to spot welder

<t>Hey Larry,<br/> <br/> Great to hear the spot welder endeavor is going well, although I can't take absolute credit for the idea. To give credit where credit is due, search way back on the old "Songs" archives to see the basic concept mentioned.<br/> <br/> I was, however, surprised how well mine wo...
