This is just for fun so dont take it too seriously... So I've read about particle beam weapons and as far as I understand its simply a concentrated beam of particles ie electrons emitted towards an object. I'm pretty sure I'm missing a big piece here when I say it (it just sound too easy) but isnt that what cathode ray tubes are? So couldnt you theoretically just build a bigger tube with a much larger power supply? Or is that the issue, that there isnt a big enough power source to do such a thing, but the idea is sound?? EDIT: Also with what I said above in mind, theoretically, if a particle accelerator would simply release the energized particles at something (I dont know, a titanium plate), is that how a particle beam weapon would work? So are particle accelerators particle beam weapons they're just simply too big for any practical use?
