Processes and Tools to Manage CERN Programmed Stops Applied to the Second Long Shutdown of the Accelerator Complex
/ Vergara Fernandez, Estrella (CERN) ; Ansel, Antoine (CERN) ; Barberan Marin, Maria (CERN) ; Bernardini, Marzia (CERN) ; Chemli, Samy (CERN) ; Coupard, Julie (CERN) ; Foraz, Katy (CERN) ; Hay, David (CERN) ; Jimenez, José (CERN) ; Mcfarlane, David (CERN) et al.
The preparation and follow-up of CERN accelerator complex programmed stops require clear processes and methodologies. The LHC and its Injectors were stopped in December 2018, to maintain, consolidate and upgrade the different equipment of the accelerator chain. [...]

New Coordination Tools to Prepare the Programmed Stops in the LHC and its Injectors
/ Chemli, Samy (CERN) ; Bernardini, Marzia (CERN) ; Birtwistle, Thomas (CERN) ; Bolognesi, Andrea (CERN) ; Brito de Palma, Bernardo (CERN) ; Bustamante, Sebastien (CERN) ; Coupard, Julie (CERN) ; Foraz, Katy (CERN) ; Kleszcz, Emil (CERN) ; Kotsolakos, Nikitas (CERN) et al.
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. [...]

CERN Accelerators Topology Configuration: Facing the Next Long Shutdown
/ Bartolome-Jimenez, Sonia (CERN) ; Birtwistle, Thomas (CERN) ; Chemli, Samy (CERN) ; Gilbert, Nicolas (CERN) ; Perrot, Anne-Laure (CERN) ; Piar, Juraj (CERN) ; Simetka, Vojtech (CERN) ; Vazquez de Prada Planas, Blanca (CERN)
The Configuration and Layout (CL) team at CERN ensures that there is a clear and coherent representation of the status of the CERN underground facilities (about 60 km of equipment) and main accelerator projects at a given point in time. In view of the major equipment changes to be carried out during the extended end of year technical stop (EYETS), the next Long Shutdown (LS2), and to facilitate the associated preparatory work of multiple CERN groups, the CL team has developed an immersive visualisation tool, displaying 360 degree panoramic images of CERN underground facilities. [...]

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. [...]

CERN’s Proton Synchrotron Booster (PSB) is undergoing a major upgrade program in the frame of the LHC Injectors Upgrade (LIU) project. During the first long LHC shutdown (LS1) some parts of the upgrade have already been implemented, and the machine has been successfully re-commissioned. [...]
