At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

As I write this report, the integrated luminosity counter for ATLAS and CMS is at 23.1 fb-1, exceeding our goal of around 18 fb-1
The LHC is in full production mode with 2556 bunches per beam and has already successfully provided 14.6 fb-1 to each of ATLAS and CMS
On 5 May, the last step in the intensity ramp-up process was completed, ten days ahead of schedule. The LHC is now filled with 2556 bunches per beam
Some 500 scientists from 147 institutes met in Amsterdam for the 2018 Future Circular Collider (FCC) week from 9 to 13 April
On 28 April 2018, 13 days ahead of schedule, the operators of the LHC successfully injected 1200 bunches of protons into the machine and collided them
The LHC operators hope to break last year’s record for total proton-proton collisions delivered to the experiments
Experiments resume at CERN’s second-largest accelerator, the Super Proton Synchrotron
Beams were circulating in the LHC by 30 March (five days in advance!), and everything is looking good for a strong final year of LHC Run II.
The 2018 proton season has started well ahead of schedule
The Large Hadron Collider has initiated the collision of proton beams for the first time this year
Protons have been circulating in the Large Hadron Collider since Friday 30 March, marking the start of the machine’s seventh year of operation
