AN electron volt is the energygained by an electron when acceleratedacross one volt ofelectric potential. This is verysmall compared to everydayenergy scale, say that of a 1 kgobject falling from a height of 1metre, which is measured inJoules (1 eV = 1.602 x 10-19Joules).In fact, 1 trillion electronicvolt (TeV) is about the energy of aflying mosquito. It is the fact thatthis energy is squeezed into aspace that is a trillion timessmaller than a mosquito thatmakes the LHC an extraordinarymachine.Given the huge number ofprotons in the beam, the totalenergy in a beam would, in fact,be equivalent to a 400 tonnetrain travelling at a speed of 150km an hour, which is enough tomelt 500 kg of copper.
