LHC Report: The final days of Run 2
The LHC is entering the final days of the four-year-long Run 2. At the end of October, the last protons for Run 2 will circulate inside the LHC. The next protons will be injected only in the spring of 2021! In the meantime, the LHC had a productive August and early September, bringing the integrated luminosity delivered to ATLAS and CMS to just above 53 fb-1. This is a new yearly record for the LHC, surpassing the 2017 value of 50 fb-1. The machine operated not very far from the maximum luminosity that can be sustained by the cryogenic system that cools the quadrupoles installed around the experiments. With the remaining days of operation, over 60 fb-1 are within reach if the machine availability remains high. The Run 2 total is now at 147 fb-1 and another week of production after the upcoming technical stop should bring us to the Run 2 target of 150 fb-1 delivered to both ATLAS and CMS. Integrated luminosities of Run 1 and Run 2. The Run 2 total is just below 150 fb-1. In parallel, the
