The High-Luminosity LHC (HL-LHC): a new milestone in CERN’s history.
The Large Hadron Collider (LHC) is officially entering a new stage. On Friday 15 June, CERN inaugurated the civil-engineering work for the High-Luminosity LHC (HL-LHC). By 2026 this major upgrade will have considerably improved the performance of the LHC, by increasing the number of collisions in the large experiments and thus boosting the probability of the discovery of new physics phenomena.
Ms. Fabiola Gianotti, Director-General of CERN inserts a time capsule at point 5 of the LHC, next to Mr Pierre Maudet, President of the State Council, Republic and State of Geneva and Mr. Stéphane Bouillon, Prefect of the French region Auvergne Rhône Alpes.
This capsule contains a document submitted by the Republic and Canton of Geneva. This historic document from 1952 is the telegram by which the President of the Council of State at the time, Mr. Louis Casai, announced to his fellow members of the Government of Geneva the news of the decision taken by the signatory states of the convention for the establishment of a European organization for nuclear research in Geneva.
