No problem. I'm assuming you meant "what will happen to that cone" instead of what will happen when it's cold... Well, didn't read this from anywhere, but it will most certainly be vaporized, of course depending on the amount of fusion fuel burned. But at any commercial-scale reactor with...

Gold-deuterium fusion would be endothermic, and besides very difficult to achieve due to the high coulomb barrier of the gold nucleus (more protons). Before they redid their page, ITER had a nice graph of fusion fuels' reactivity versus temperature, and it had "catalyzed D-D" as one of the...

Yep, the neutrons are necessary. Meteor impacts, even when on such a large scale, release the energy in a different way and no free neutrons are emitted. In an impact event, the kinetic energy of the meteorite is converted to heat. It might look like a nuclear explosion and have same magnitude...

C-14 production from beta plus decay would happen from nitrogen-14, which is a stable nucleus, so C-14 won't be produced by beta + decay, at least not directly by it. In nuclear detonations, the neutrons are necessary to induce the n + N-14 --> C-12 + H-1 reaction. If you had a neutron-free...

Antimatter production usually involves two elements: the other being protons (i.e. hydrogen nuclei), which are accelerated to relativistic velocities, and the other being a heavier element with high Z (proton number). It doesn't really matter which specific element the target is made of, just...

You are propably looking for the Large Hadron Collider, or LHC. See the wikipedia article http://en.wikipedia.org/wiki/LHC They activated it on 10 September 2008, but only for testing. No particle collisions at full power took place. An accident, involving a magnet quench and loss of...

You have the equations right, but used percentage wrong. Stop reading now if you want to figure it out yourself. Because kinetic energy increases, you should express W = 1.47 instead of W = 0.47. This yields a solution which is >1, which means that the energy really increases. If your...

First: be careful on whether writing "resistance" or "resistivity", since these two are different quantities. Resistance is measured in ohms, and concerns a whole electrical component. Resistivity is the resistance of a material. In the following equations you can replace \rho (resistivity) with...

Thanks for the reply, much useful information in that. About these reactions: something has to be wrong in my calculations. I've calculated that 10B + n --> 11B would be exothermic and yield 11.5 MeV. This seems quite an energy to me. That's approx. 111 TJ/kg. The energy density rivals that...

I have a decent understanding of neutron-induced reactions in heavy nuclei (fission, capture), but less so when light nuclei are involved. I do know of Li6 + n --> He4 + T and the Li7 equivalent. Those reactions are more like nucleus splitting (fission). My question is: do neutron capture...
