World's largest accelerator makes record particle collisions
Large Hadron Collider, the world's largest and most powerful particle accelerator has achieved a new record for luminosity, or the total number of potential collisions, in its 2017 run. Last year, LHC obtained 40 collisions at each bunch crossing, with each bunch containing 100 billion particles. In 2017, up to 60 collisions were produced at each crossing, setting new records.
