Re: Wieder Labs?

I got them at Sharpe Products, and I think that's the cheapest place unless something has changed recently. It was some $30 for two 6" hemispheres (prices of many years ago) which I found quite affordable.

Re: Is there a device that chang the frequency of an AC current ?

<t>If you manage to actually find such a device, it will probably be very expensive (I've never seen a retail product that offers exactly this). You can gut one out of some other power supply and use it if you can figure out the control interfaces, but I've never heard of a complete product that doe...

Re: Polarity of an xray transformer?

Based on the schematic, it is an AC output so you add external rectification and can pick the polarity by how you set that up.

Re: A couple BTI bubble detector runs

<t>Looks great, and certainly has fusion going on!<br/> <br/> There is no reasonable doubt with 25 counts that fusion is occurring... that comment is discussing the accuracy of the actual count rate measured. When radiation counting, the counts recorded in some given time frame has an uncertainty of...

Re: Limited budget. Is this a good way to acquire money?

<t>Another approach is to just get a part time job. Given that it'll take year(s) to build a full neutron producing fusor, if you run the numbers even with a pretty insignificant number of weekly hours, you can keep up with the project's costs.<br/> <br/> That's how I paid for 80% of my high school ...

Re: Wieder Labs?

Re: Ion gun fusor

There are probably thousands of posts here discussing ion guns. In fact, you posted in a sub-forum practically dedicated to answering your question. I'd start there.

Re: Is this a good Demonstration Fusor Chamber design ?

To attach a conflat viewport, you attach a conflat flange to your chamber, then attach the viewport with a copper or viton gasket. You cannot weld a viewport on, it would destroy the viewport to get it that hot.

Re: Reuter Stokes Proportional Counter

Because GE told you it is...

"The part RS-P7-0805-127 would be a B-10 lined proportional counter, filled with ~0.8bar of Argon as quench gas. According to our files, this detector was made in 1976."
