Proton collisions at the LHC end on a high(-luminosity) note 💫 During this year, an exceptional volume of data was collected at a collision energy of 13.6 teraelectronvolts (TeV). The integrated luminosity, which relates to the number of collisions recorded in a given amount of time, reached 125 inverse femtobarns for the ATLAS and CMS experiments, and the total is more than 520 inverse femtobarns since 2010. Watch to find out more about what this means. 👇 | CERN

This is the CAST experiment - hunting for hypothetical "axion" particles that could be produced in the centre of our star ☀️ Find out more about this experiment: https://home.cern/science/experiments/cast | CERN | Facebook
