A few days ago the LHC achieved a new particle collision energy record with 13TeV in a series of “set-up” experiments.

Yippee. That was well worth waiting for. The original plan was to have 13 TeV much earlier, but the meltdown of the LHC in the first few months delayed implementation for a couple of years. In case you’re wondering, the previous energy for proton-proton collisions was 8 TeV. The increase to 13 TeV isn’t the only improvement. We’re also seeing better focussing and larger numbers of particles circulating, together resulting in a very significant increase in the number of collision events, but done in such as way as to not overload the sensors with multiple collisions at the same time.

So far as I can tell, there are no firm plans yet to increase the proton-proton energy beyond 13 TeV when this set of runs is finished. I heard a tentative proposal to make minor changes later, and a more radical tentative proposal to switch it from proton-proton to electron-electron collision in the distant future.
