4. Does TE/VSC have all needed information from LIU
Documentation
Launch Safety Agreement - done
List of hazards - done
Safety File Part 1: Descriptive - done
Safety File Part 2: Demonstrative – to do
Functional spec for impedance reduction – to be closed
Functional spec for aC coating – under approval
ECR for impedance reduction – to be closed
BE/RF need to measure EYETS shielding solution
ECR for aC coating – under approval
Risk assessment and mitigation for aC – under approval

5. Are TE/VSC preparatory activities within expected timeline?
aC coating for EYETS
Validation of 13 m MBB string in 181
Validation of QF profile coating in 181
Validation of ozone cleaning of contaminated St.St. in 181
Setting up of long test station in 867 (MBB, QF, SSS girder) – done, trails to start.
Job open for manufacturing of replacement drift chambers – done, manufacturing ongoing
Procurement of components for benches (tunnel & 867) – ongoing (90%)
Setup of benches in 867 vacuum lab to do – draft layout done, trial with LEP trailer to do
Flange Impedance Reduction for EYETS.
Shielding design finalised for EYETS implementation
Based on design applied during 1999 impedance reduction – ECR to be closed
Cannot wait for RF measurements/simulations on flexible fingers
Cannot wait for soft clamp tests (by-pass of insulated flanges)
Detailed design and manufacturing will be tight – request for quotation ongoing
Planning for EYETS
All tunnel activities in same arc – BA4 to BA5
Takes account of learning objectives - time margin for surprises – 55 day window ok
VSC activities are staff dominated
Methodologies will be confirmed – eg SSS girder/individual magnet handling - ongoing
Drift chambers manufactured and coated in advance of EYETS - ok
Detailed planning to be elaborated with EN-ACE-OSS – draft planning for discussion

6. Has all the LIU required work been declared in PLAN
Has all the LIU required work been declared in PLAN? (Are all dependencies on other groups defined…?)
Dependencies on other groups identified during costing exercises for aC & flange impedance reduction in 2015.
Weekly deployment meeting with representatives of involved group TE-MSC, EN-ACE-SU, EN-HE, TE-VSC, BE-RF, EN-ACE-OSS, HSE-RP,
Data entered in PLAN (EYETS, LS2) – some overlapping identified (same data by other Groups) - to be checked and cleaned

7. Are the LIU EVM timeline & budget correct?
Annual work units based on APT data (agreed budget)
Need to establish EVM data to reflect deliverables – not yet done 
99273: Committed in 2016 = 447k + 48k to come (396k budget).
65332: Committed in 2016 = 7k + 80k to come (163k budget).

8. Are the VSC-CONS items linked to the operation of LIU approved, in time and within specification?
All TE-VSC SPS Cons requests up to 2020 have been approved
Ion pumps, ion pump power supplies, spare chambers, flanges, bellows, valves, pumping group renovation, …ok, ongoing
On-going clarification of SPS controls consolidation (PLC replacements) request. Postponed during 2015 CONS arbitration exercise but now understood to be within ‘CONS envelope’ attached to HL-LHC during C&S – VSC controls request doc in preparation
