3. Master schedule of LS2
M. Bernardini,
EDMS

4. Main infos / constraints of LS2
Main dates
End of physics: end of week 49 ( )
Xmas 2018: standby at 20 K
Cryo-conditions back for quench&tests:
Start of warm-up: (S1-2); all sectors warm:
First cool-down (S4-5): ; all sectors ready for powering
End of training quenches:

5. LHC-LS2 global overview
M. Bernardini,

6. LHC-LS2: open points beginning of LS2
Definition of the tests to be performed at the beginning of the LS2: powering, training, which sectors …?
Definition of the cryogenics conditions during the Christmas closure  Cryo presently included and it fits in the LS2 baseline
QRL X-rays: a cartography of the scaffolding installation should be defined, to prepare LS2

LHC machine Schedule for YETS, INDICO

7. LHC-LS2: open points end of LS2
Definition of the cryogenics conditions during the Christmas closure  Cryo presently included and fits in the baseline
Pressure tests before the cool down starts  The strategy for the pressure validation test should be defined well in advance, as well as the procedure to apply, and the necessary derogation requested
Validation of redundant UPS power distribution during the EYETS Lesson learned during EYETS: the new procedure is convenient for most of the stakeholders.  final validation with TE-VSC needed (Volotek power supplies and Bayard-Alpert gauge filament damaged during EYETS tests)
Number of training quenches per sector , 7TeV
End of LS2

Challenge to manage a very large number of tasks!
Non-LHC operation will continue (with some reduction)!
New projects are growing!
Impact on most activities of the CRG group (group-wide preparation is required!) 8

Pressure tests, if any; Sectors cooling down, commissioning
Emptying (LHC acc.), securing helium inventory, leak testing (localising potential damage on QRL bellows and/or DFB gimbals), warming up (3 months)
(2013) 2019
(2014) 2020

15. Consolidations master schedule during LS2

16. Lessons learned / recommendation from LS1
LS1: 28 projects/tasks, 27 MCHF budget, 57 FTE
Summary of LS1 OMP review (\\cern.ch\dfs\Departments\TE\Groups\CRG\CRG OMP\2014\OMP \OMP special_post LS1_summary_Conclusions.pptx)
Preparation phase improvements
Improvement of schedule for co-activities (LHC / non-LHC).
Improvement on tracking and quality assurance
Summary of LS1 projects review (EDMS )
An explicit coordination structure should be planned in the preparation phase for all projects.
Tools to track, follow and evaluate the projects should be defined during the preparation phase. A baseline shall be defined and communicated to all stakeholders and the schedule shall be regularly updated and communicated to all stakeholders.
A risk analysis should be performed for the larger projects. Specific preparations should be made to cope with the possible occurrence of unexpected problems.
The transition between the successive phases shall be better planned and coordinated, in particular the start of operation. The handover of the systems between the teams shall be better identified with clearly identified systems being formally transferred.

17. Roadmap of preparation for LS2
LS2 has many characteristics of a project: start date, end date, identified listr of tasks
Can be treated as a project with the relevant tools
Identify all LS1 projects/tasks, responsibility and contributing sections (in progress)
Evaluate resources needed for each contribution and pre-define preferred strategy (rep- schedule, resources, etc.)
Decision on tasks / projects
Prepare the tasks (baseline, resource allocation, responsibilities, tracking tools, coordination, etc.)
Perform project / task, monitor project / task
In parallel: define the tools to prepare, monitor and report the activities
Proposal for regular reviews and progress (12/2017; 03/2018; 06/2018; 09/2018)

19. Official LS2 priorities
