Please be patient with my ignorance. :) I have just learnt in the LHC's own website ( http://lhc-machine-outreach.web.cern.ch/lhc-machine-outreach/beam.htm ) that their proton beams traveling at 0.999999991c carry about 362 MJ of energy, equivalent to 77.4 kg of TNT. These beams seem to be composed of 2808 bunches of protons, so I assume each bunch packs 128 kJ ---about 7 times the muzzle energy of a .50 BMG bullet. Sure my question is easy and possibly silly, but I'm puzzled. :) Why doesn't the impact of these beams against a target cause something similar to a 77.4 kg-TNT equivalent explosion, or at least the effect of an ultra-rapid fire, super-heavy machine gun shooting 2808 projectiles at point-blank range, please? (If it's not the case, please apply to any high-energy particle accelerator "shooting" at targets, or to accelerators of heavier ions, if you don't mind.) Thanks in advance!
