On 8 October, the increased intensity beams generated an average of 150 collisions inside the experiments. This image shows an event – a collection of simultaneous collisions – reconstructed by the CMS experiment. In total, 206 collisions were recorded, as indicated by the 206 yellow circles. The lines show the 9 381 tracks of charged particles generated by the collisions. Image: CMS

Earlier this month, the accelerator propelled particle bunches containing more than 230 billion protons (2.3 x 1011): 40% more than standard bunches. As they collided inside the experiments, these bunches generated an average of 150 collisions, compared to around 65 collisions during ordinary operations. These tests, which ran for several hours, were aiming to study the lifespan of beams in collision mode, in conditions similar to those expected in the HL-LHC... continue reading on CERN News
