Re: Typo
Hm. Slight confusion, here. A proton accelerator produces photons from the collisions, which is the light that the detectors pick up. However, to be clear: it's the beam of protons that smashes into the sample, producing the light. I've made it clearer in the piece.
Don't forget to email corrections@theregister.com if you spot any problems, so they can be fixed quickly.
