Re: American Institute of Physics free online access during October

Thanks for the heads up! I will definitely make use of this. It is a letdown to find something interesting and then find out I will have to pay when I'm not even sure if the content is going to be useful to me.

Re: High voltage diode

<t>Carl,<br/> I have a potential transformer that I use in my power supply, and it has a nameplate specifically stating what the breakdown voltage is (mine is rated at 500kv). These things are connected to lines that will have substantial voltage spikes at times and (at least all I have seen) are sp...

Re: Archived - Fusor progress, info & photos

<t>I purchased a 6" spherical chamber from the same source and although the welds may not look as pretty as some would prefer, I have had no problems achieving an acceptable vacuum for the experiment I purchased it for, although in the E-4 torr only and without appreciable heat. It was supplied to m...

Re: Post Fukushima Radiation in Japan

The Cs137 is certainly from a reactor, but the K40 may be natural. I can't wait to see the spec whe n you get it up. Thanks again for the update. Hope you're having some fun and sightseeing.

Re: Post Fukushima Radiation in Japan

Thanks for the report. With dose rates this low, the increased health danger is very low. I know a few rock collecting locations with significantly higher natural background rates here in the U.S. Do you have the means identify any isotopes where you've been?

Re: Tig welding problems (air leak)

<t>Not to argue, Jerry, but I should have said it works INFINITELY BETTER than a model that cannot afford and will never be able to afford. I have been TIG welding for many years (actually certified many years ago) and I cannot tell the difference now between this welder and the expensive Miller wel...

Tig welding problems (air leak)

<t>I purchased an inexpensive Tig welder/plasma cutter from ebay so I wouldnt have to do all my welding at work. I was having difficulty getting as nice a weld as the higher quality Miller welder at work. My bead would look "bubbly" and burned. I also noticed that my argon supply was going much quic...

Re: Historical film of Los Alamos

<t>Thanks for this wonderful link. You always seem to give us such rewarding posts.<br/> <br/> I have long been fascinated by the scope and breadth of the Manhatten Project. It is amazing to think of the engineering and scientific accomplishments brought forth by all the people involved. Since readi...

Re: Some photos of scintillators in a radiation field

<t>Very beautiful photos, but I'll bet its nothing compared to seeing it in person. I've worked in fission power since the 80s and I still think the Cerenkov glow around a fuel bundle is amazingly beautiful but I have yet to see a photo that completely does it justice. Thanks for posting this. I am ...
