GENEVA (AN) — The world’s biggest atom smasher will restart for the first test beams in September 2021, a half year later than planned, and will operate for an extended run from the start of March 2022 until the end of 2024, the European Organization for Nuclear Research said on Friday.

Managers at the international organization, known by its French acronym CERN, agreed to the new operating calendar with the approval of a governing council of 23 member nations. The council also was responsible for reappointing Fabiola Gianotti, an Italian physicist, to a second five-year term as CERN’s director-general starting in January 2021.
