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.

Last week, the accumulated integrated luminosity reached the target value for 2016 of 25 fb-1 in both ATLAS and CMS
The LHC has been in great shape over the last few months, delivering over 20 fb-1 of integrated luminosity before the ICHEP conference
A new bunch injection scheme from the PS to the SPS allowed the LHC to achieve a new peak luminosity record
The LHC is off to an excellent start in 2016, having already produced the triple the luminosity production of 2015
Summertime, and the livin’ is easy… not so for the LHC, which is just entering four weeks of full-on luminosity production
Electrical equipment that was damaged by the beech marten has been repaired. The LHC is back on track with ever higher beam intensity.
The recommissioning of the LHC is going well: the machine has delivered first pilot Stable Beams collisions.
With the machine back in their hands since Friday, 4 March, the LHC operators are now performing the powering tests on the magnets
The proton-lead run was an unqualified success and a testament to painstaking preparation by the ion team
Proton-ion operation has become routine for the LHC operation crew with all seven LHC experiments simultaneously taking data for first time
The LHC starts the New Year facing a new challenge: proton-lead collisions in the last month before the shutdown in mid-February
Record number of 2,748 proton bunches injected into the LHC giving a record beam intensity of around 2.7 x 10^14 protons in both beams
