Particle physics takes the long-term view. Originally conceived in the 1980s, the LHC took another 25 years to come into being. This accelerator, which is unlike any other, is just at the start of a longer programme, which is expected to run for another 20 years.
Even now, plans are being hatched for a large-scale upgrade to increase luminosity and thereby exploit the LHC to its full potential. The high luminosity LHC is CERN’s number-one priority and will increase the number of collisions accumulated in the experiments by a factor of 10 from 2024 onwards…
