Lay Summary (French)

Contribution de SNF-FLARE aux coûts annuels de maintenance et d'exploitation de grandes expériences au LHC du CERN où les instituts suisses ont une participation de recherche (ATLAS, CMS, LHCb).
Lay summary
Ce projet couvre les frais de fonctionnement et de maintenance que les instituts suisses contribuent aux expériences où ils participent (ATLAS, CMS et LHCb). Les contributions sont proportionnelles au nombre de scientifiques qui participent à chaque experience, par rapport au nombre total des scientifiques. Elles sont calculées internement dans les expériences sur une base annuelle et elles sont approuvées par un comité de ressources du CERN désigné pour leur examination (Conseil d'examen des ressources).

This FLARE proposal aims at covering the 2021-2024 Swiss share of the maintenance and operations (M&O) costs for the experiments at CERN’s Large Hadron Collider (LHC). As a joint request from all Swiss groups active at LHC, it is coordinated by CHIPP (Swiss Institute of Particle Physics) since 2006. It summarizes the Swiss contributions to the LHC detectors, explains CERN’s concept of M&O as defined in Memoranda of Understanding, and gives an overview of the costs that Switzerland is expected to cover in the years 2021-2024. While the 2021 numbers are based on the decisions of the LHC Resources Review Boards (RRB) in October 2020, the request for the later years is based on extrapolations from the 2021 values.The budgets approved by CERN’s Resources Review Boards in October 2020 imply a mandatory total Swiss contribution for 2021 of 915 kCHF, distributed over the three detectors with Swiss participation as follows: 238 kCHF for ATLAS, 456 kCHF for CMS, and 221 kCHF for LHCb. Based on these numbers and on the extrapolations provided by the experimental collaborations, the costs for the years 2022-2024 are extrapolated to a total amount of 3’729 kCHF, with similar sharing among the experiments as in 2021.
