What about LS2?
The LS2 project include the activities across the LHC, Injectors and LHC experiments:• Resources levelling across the accelerators one of the main challenge of LS2 !!!• The activities will be declared in Plan, with a similar approval process as LS1.
Practical issues:• Temporary storage areas and “bases de chantier” will be installed at the earliest 6
months before, and dismounted at the latest 6 months after LS2;• Buffer zone availability: most probably the existing areas are not sufficient;

• MB replaced by 3 cryo-assemblies, installed and aligned independently• 11 T dipoles assembled with an angle of 2.55 mrad relative to each other and shifted by
0.8 mm towards the center of the LHC to minimize loss of mechanical aperture• Cryostat for the 11 T dipole following standard LHC design• Short connection cryostat: creates space for collimator and warm beam vacuum sector;
continuity of powering and cryogenics along the LHC arc• Collimator: 0.8-m-long active part – tungsten – 1.34 m with transitions and expansion joints• RF-shielded gate valves allow for independent operation of cold and room temperature

Other infrastructures/works• Minor works for Cold Powering P7• Possibility to advance civil engineering
(excavation and buildings) in P1 and P5 and use of surface buildings for storage
• Installation work compatible with maintenance and consolidation work
• Importance of SM18 upgrade
Click here to add footer 32
Conclusions• Identify and prepare work that can be done
in LS2 on the time frame allocated for which the technology/solution is mature and can not bring any risk to the run 3 start date
• Integrate as early as possible our work planning with other LS2 Works
• Work together with the consolidation team to optimize resources
