Science Focus
original post »Earlier today, science returned to the tunnels of the LHC with the first collisions dedicated to physics in over two years. At 10:40am local time (4:40am EDT), detectors started taking data from 13 Tera-electronVolt collisions.
These weren't the first protons we've accelerated to these energies; they weren't even the first collisions at these energies. For the past several weeks, the machine's operators have been ensuring that all the upgraded hardware in the system behaved as expected and gained experience with controlling protons at these energies. As part of that process, some collisions were performed to check out the relevant hardware. Since the collisions were happening anyway, the teams behind the detectors captured what was happening.
The real change today is that the collisions weren't performed in order to test any hardware—they were purely done to gather data. And the detectors were definitely capturing data.
