Thanks mathman. I did some research and first came up with MCNP but that is not available to the public but then noticed GEANT4. I had actually compiled and installed GEANT4 a few years ago on a Linux box of with the intent of modeling geometry of a linac. I forgot that it has the ability to...

Are there any good models, software or codes that can predict the probabilities of nuclear reactions where an atom of a given type strikes another atom of another type with a given energy? Or is this information only obtainable experimentally? To further clarify, I am interested determining...

Thanks for the responses. So the 63.5 percent is from the formula for Carnot's theorem. I've seen it before but I think I've got it commited to memory now by seeing it stated so simply. Marlin

I am interested in building a thermal solar collector. I'm mostly interested in using the heat directly but there's always a need for electricity. The trouble is converting heat into electricity is pretty inefficient no matter how you do it. Consider a peltier device. A typical one, depending...

That makes sense.

Price is outstanding. Looks like you can get a gram of Am-241 oxide for $1,600.

Thanks. After posting I thought about Americium because it's common in smoke detectors. It is a bit expensive at $160 per milligram but I think I can produce small amounts of product and scale it up. 1 gram of Americium would generate 3.5 Ci. I'm guessing that amount would cost far less...

I would like to pursue an idea that involves transmutation of elements using an alpha emitter. I figure that the production rate I would like to achieve would require about 5 Ci of radioactivity. What would be a good candidate, i.e. least expensive and reliable supply with a half life of > 60...

No, but now that you mention it that seems blatantly obvious. Cheap too. Thanks!

It will be applied to an electrode that is energized with RF. The purpose of the paste would be to smooth over the joint because the electrode will be made in pieces and runs the length of the accelerator as in an RFQ linac.

For an accelerator application I need some paste that can conduct electricity decently, but will also not outgas under a vacuum and have a cost of under, say, $20 per gram. It doesn't matter if the paste solidifies or remains malleable. I have thought of copper and silver paste but not sure...

First off, the battery life remaining indicators are not very accurate, so what is displayed often doesn't show the reality. For example, I've got an ancient RAZR and if it's very low but I only charge it for ten minutes it displays fully charged but only for a short while. Ideally the...

Googling around, it looks like a bone densitometer

For a cyclotron application, I want to make a magnetic circuit using permanent magnets. The attachment shows a diagram of the circuit. It has two neodymium magnets "in series" and mild steel bars extend to duct the circuit around to two disk shaped pole pieces (red and blue). The diagram is...

I was wondering at the remarkable fact that when an atom has an extra electron it is then possible to apply forces to it to accelerate it. What I find remarkable is the fact that even a heavy ion like mercury where the nucleus is many orders of magnitude more massive than the one electron that...
