Plan et priorités pour les 3 ans 2016 -2018 Consolider le cas de CLIC, développer un plan d’installation en plusieurs phases ØEngagements et priorités du LAPP • Continuer la R&D MICROMEGAS résistifs. Ambition Construire un calorimètre de 50 x 50 cm 2 en collaboration avec d’autres instituts • Stabilisation d’un module d’aimant de FF de taille réelle • QD 0 STABILIZATION: one of the most critical aspect of the new layout. QD 0 will be longer (4. 7 m) but can be split in 2 -3 elements (each length ~ 1. 5 m; always try to minimize the QD 0 mass; correlation/matching of the 2 -3 stabilizing systems) • Exploration du potentiel de physique et optimisation du détecteur (CLIC)

CLIC strategy and objectives 2013 -18 Development Phase 4 -5 year Preparation Phase Construction Phase Develop a Project Plan for a staged implementation in agreement with LHC findings; further technical developments with industry, performance studies for accelerator parts and systems, as well as for detectors. Finalise implementation parameters, Drive Beam Facility and other system verifications, site authorisation and preparation for industrial procurement. Prepare detailed Technical Proposals for the detector-systems. Stage 1 construction of CLIC, in parallel with detector construction. Preparation for implementation of further stages. 2018 -19 Decisions On the basis of LHC data and Project Plans (for CLIC and other potential projects), take decisions about next project(s) at the Energy Frontier. 2024 -25 Construction Start Ready for full construction and main tunnel excavation. January 22, 2016 Commissioning Becoming ready for datataking as the LHC programme reaches completion. 12

Depuis 2004 le LAPP a développé une expertise sur la mesure et le contrôle de nano-vibrations unique en France et rare dans le monde Ambition Etre l’acteur majeur dans le milieu des accélérateurs dans cette thématique, au niveau européen et mondial. Stratégie Nouer de multiples collaborations scientifiques dans le milieu accélérateurs (ATF 2, Super. B, DAFNE etc. ) Valorisation • Capteur innovant développé dans le cadre de LAVISTA • Unique possibilité de valorisation d’un développent technique au LAPP depuis 40 ans • Nécessité d’investir des moyens humains (LAPP + extérieurs) au delà du projet scientifique.

After the strategy update => context From the European strategy document: “… Europe needs to be in a position to propose an ambitious post-LHC accelerator project at CERN by the time of the next strategy update” This is reflected in the CERN financial plan in which FCC and CLIC fuse into a single budget line from 2020 onwards 2019 -2020 Only one CERN energy frontier project as of 2020 January 22, 2016 15
