The LHC and its Injectors are submitted to an overall lifecycle of three to four years of physics delivery to Experiments with a two-year long stop, also known as Long Shutdown (LS). The years of physics delivery are ended by a programmed stop for the immediate preventive and corrective maintenance, also known as (Extended)-Year-End Technical Stop - (E)YETS. [...]

Integration, Configuration and Coordination: from Project to Reality, at CERN
/ Barberan Marin, Maria (CERN) ; Bartolome-Jimenez, Sonia (CERN) ; Bernardini, Marzia (CERN) ; Birtwistle, Thomas (CERN) ; Chemli, Samy (CERN) ; Corso, Jean-Pierre (CERN) ; Coupard, Julie (CERN) ; Foraz, Katy (CERN) ; Grillot, Serge (CERN) ; Muttoni, Yvon (CERN) et al.
The rigorous process in place at CERN to approve and follow-up the implementation of any modification of the LHC machine and its Injectors is presented in this paper. Our methodology implies the support of three teams, in charge of the configuration management, the scheduling and safety coordination, and the 3D integration studies. [...]

Lessons Learned From the First Long Shutdown of the Lhc and Its Injector Chain
/ Foraz, Katy (CERN) ; Barberan Marin, Maria (CERN) ; Bernardini, Marzia (CERN) ; Coupard, Julie (CERN) ; Gilbert, Nicolas (CERN) ; Hay, David (CERN) ; Mataguez, Simon (CERN) ; Mcfarlane, David (CERN) ; Vergara Fernandez, Estrella (CERN)
The First Long Shutdown (LS1) of the LHC and its Injector chain, which started in February 2013, was completed by the first quarter 2015. A huge number of activities have been performed; this paper reviews the process of the coordination of LS1 from the preparatory phase to the testing phase. [...]

Schedule Evolution of the Linac4 Installation During the Lifetime of the Linac4 Project and Connection Forecast
/ Coupard, Julie (CERN) ; Berjillos, Aurelio (CERN) ; Corso, Jean-Pierre (CERN) ; Foraz, Katy (CERN) ; Nicquevert, Bertrand (CERN) ; Paulat, Emmanuel (CERN) ; Vretenar, Maurizio (CERN)
The new CERN linear accelerator Linac4 started the installation phase in 2010 after the delivery of the new building and tunnel by the civil engineering and was inaugurated six years later. It will be connected to the CERN accelerators chain and replace the current proton linear accelerator, Linac2, during the second long shut-down (LS2) of the Large Hadron Collider (LHC) in 2019. [...]

CERN is currently carrying out an ambitious improvement programme of the full LHC Injectors chain in order to enable the delivery of beams with the challenging HL-LHC parameters. The LHC Injectors Upgrade project coordinates this massive upgrade program, and covers a new linac (Linac4 project) as well as upgrades to the Proton Synchrotron Booster, the Proton Synchrotron and Super Proton Synchrotron.
