Grams of WHAT? Grams of matter converted into energy according to E = mc^2 EricP is right on the money. Nuclear binding energy is released by fission and the bits remaining afterwards weigh a little bit less. The mass difference becomes kinetic energy and electromagetic radiation. A nanogram of mass annihilated would release about 90kJ - barely enough to boil the water needed to make a small pot of tea. Regards, Martin Brown

That way, >you might be able to recover a tiny bit of honor. Serious lasers, like NIF, have to be very careful about dust. When they fire the laser, dust on optics can explode and blast tiny craters in the glass. I think NIF is the world's biggest clean room. John

It is easier to place most of the manufactuing process in a vacuum and eliminate the dust particles. {Hint: dust cannot float in a vacuum to land on the wafers, but drops like a rock to the floor.}

Try semiconductor particulate or semiconductor contamination or things like that. "Dust" is sort of lowbrow to the people who write papers about this. John |
