Re: F.I.C.S. Construction - First Plasma

<t>Steven,<br/> What is meant by "water cut" glass disks? Approximately how thick and large in diameter are these disks? I can visualize grinding and polishing them into a 'D' shape to provide a view along one side, but wonder what part they play.<br/> <br/> Also, are these disks between the ion gun...

Re: MKS 925 MicroPirani Interfacing

<t>Hi Steve,<br/> Yes, I realized later that I confused vacuum gauges when writing. Main thing was that the MKS software was neat, simple and worked with my screen reader. Many programs are not accessible, or cludgy with screen readers because they are written fancy with screen graphics for sighted ...

Re: MKS 925 MicroPirani Interfacing

<t>Hi Steve,<br/> After reading your post and comment about the software, I just had to test it. Simple software may not be visually attractive, but it is often best for people using adaptive technology. I downloaded, installed and ran the software using my JAWS screen reader and it worked great. Th...

Re: Freeware Detector Program, Digital Geiger Counter

<t>PRA 4.0 is a simple, effective program. Marek even modified the current version so that it would work better with my JAWS screen reader. The program works as a simple pulse counter and the trigger threshold can be set from 0 to 100 to elliminate noise and just catch the pulse peaks from an audio ...

Re: Best, simplest (cheapest) neutron detector for pulse neutrons

Hi Steve, I tried the link and got a "warning, empty page" message. On my first try, Adobe said it was an empty document. Lately, I get this a lot with PDF documents, though I'm using Adobe Reader 9x.

Re: Ion Steering Fins - Experimental Results

<t>Tyler,<br/> I can't see your pictures, but what I've read clicked today as I was reviewing a post on Doug Coulter's S/E/T forum. It was a post by Steven Sesilman (Austrailia, may have his last name spelled wrong) about a different concept in fusion, aligning the ions to create optimum conditions ...

Re: Bell Jar for Demo Fusor

<t>Seriously Ed, the $70. bell jar sounds like junk. I tried to read the "manual" for the second one and it wouldn't come up in Adobe. I wasn't impressed by either, and I'm certain somebody here has leads on much better deals that won't implode when your group gets started. Remember to include a pol...

Re: Ionization of Deuterium

<t>Hi Frank.<br/> Yes, not something anybody rational would want, contaminating the insides of a fusor with americium. I hadn't thought that aspect of my question through. The possibility of electrons or any other heat source vapourizing americium ... a manifestation of my ignorance.<br/> I suppose ...

Re: Ionization of Deuterium

<t>Dan, I can't appreciate the graphics or graphs, but your post brought up a question. You mention that ionization in a simple fusor can start by incoming charged particles. Have some fusioneers tried mounting isotope sources inside their fusors at the D2 injector? Pardon my ignorance, but would su...

Re: Freeware Detector Program, Digital Geiger Counter

<t>Yesterday I was reviewing test data I'd collected on the Monitor 4. I'd forgotten about some data using PRA 4 and an alpha button. The averages for 10 minute runs were as follows:<br/> <br/> X1=52216.5 X10=53439.5 X100=53252<br/> <br/> This PRA run was the first that showed the count numbers all ...
