LS2 Ramping-up as of Phase 1 (or after t0)

A gradual and cautious re-start plan

toPhase 0 Phase 1 Phase 2

Safe-mode and otherurgent activities

Resume gradually, startingwith LS2, accelerator anddetector upgrades, urgentsite and building work

Ramp-up to “unlimited”access may be completed by mid-September

Number of people on sites includes CERN’s personnel as well as contractors.

Personnel involved in LS2, accelerator and detector upgrades, urgent site and building work will come back to site gradually as of 18 May.

The rest of personnel will come back gradually as of 2nd week of June.

Personnel will be called back by supervisors.

Closing remarks

Injectors & LHC were on schedule…Few components on the critical path were followed closely.

No showstopper identified, full span of activities and resources.

Two additional months requested by LHC Experiments to be used for additional magnet training to see potential for operation @ higher energy.

CERN went on Safe mode due to COVID-19 mid-MarchAll equipment & infrastructures put on Safe mode within 2 weeks!

Closing remarks

LS2: the main driver of CERN Ramping-upPhase 0till mid-May: used to implement COVID-19 Safety measures, adapt

procedures, tools and schedules. Successful with intensive field coordination and safety follow-up (tunnel and surface).

Phase 1since mid-May: LS2 activities restarting according to new schedules. ~3 months impact of COVID-19 Safe mode → No snow-ball effect.

LN2 and LHe start deliveries mid-July’20 → LHC cool down to start mid-September’20.
