Consolidation activities for TE-ABT “Consolidation Day” – 12 September 2013 V.Mertens

1. Consolidation activities for TE-ABT “Consolidation Day” – 12 September 2013 V.Mertens with many thanks to J.Borburgh, E.Carlier, L.Ducimetière, T.Fowler and B.Goddard Outline: Assumptions and annotations Ongoing activities – changes 2014 – essential activities 2015 – 2020 – proposals Concluding remarks • Scope: • Period until LS2 included (LS2 “baseline” is 2018) • Not: activities started in or before 2013 (unless significant budget changes) • LHC, injectors, AD, NA (NA: not concerned; not ISOLDE) • Including: • Any significant changes to existing budget allocations for activities • Essential activities which must start in 2014 and why these are considered as essential • All other proposed activities for 2015 to LS2 (2020 ?) with time scale and budget estimates and why these activities are needed • Any support needed from other groups • Risk incurred if the work is not done (using existing risk analysis) 1/8

2. A view back … In-depth analysis in 2010 for “consolidation to keep injectors running another 25 years”, resulted in a fine-grained table (124 specific items, with totals of 10 – 1500 kCHF each). To that to add another 30 items specified before that time, and partly already ongoing. Since then ca. 40 of these got approved and started, a couple of them superseded by other projects (LIU, …), or cancelled since equipment is no longer in function.

3. Assumptions (partly to confirm) and annotations • BE-CO confirmed that maintenance (“consolidation” ?) of existing CO infrastructure (FEC, CPU, hardware modules) will be covered by CO  not included in our estimates. • Requests for additional CO equipment are included in our estimates, as agreed. • In certain areas (e.g. B359) cable ladders are (over)full. Requests for new cables can lead to extra cost if no clean-up is done before. The extra cost for such additional infra-structure is not included in our estimates, but supposed to be covered by EN-EL • (to be confirmed). • Some ABT consolidation activities get induced by consolidation in other groups (e.g. CO), although the risk for ABT equipment is low. How is that decided – a “PLAN” ? • To lighten the accounting and increase flexibility we suggest that selected items (like refurbishment of 1-2 septa/yr, build spare LEIR kicker/septum; per item typically < 50 kCHF) move into exploitation. These items were thus removed from our tables. • Requires slight increase in recurrent budget, by some 180 – 200 kCHF (5 %). • The work which can be achieved between LS1 and 2020 is conditioned by the actual length of the winter breaks, and the actual start/length of LS2.Many items require at least a 6 week stop; proposed items and profiles rely on that. • Some activities are waiting for approval of technical proposals by HSE (fire prevention). • Some activities are tightly linked to projects (like LIU). Budget source must be clearly identified to avoid surprises, and funding must be available when project activities start.

4. Ongoing activities – changes Presently 34 items are approved (with work actually started on 24 of them). Overall situation looks like this: Main reason for changes: focus on completing huge LS1 programme within time line(s). 3 activities with most significant changes in 2013/2014 (grouping several sub-items): incl. pre-2013 kCHF Year Present New kCHF V.Mertens – Consolidation activities for TE-ABT / “Consolidation Day” – 12.9.2013 4/8

5. 2014 – essential activities Not repeating items already approved (previous slide), also if start postponed to 2014. kCHF Total: 750 150 (2014) kCHF V.Mertens – Consolidation activities for TE-ABT / “Consolidation Day” – 12.9.2013 5/8

6. 2015 – 2020 – proposals (I) To ease the overview related activities were grouped together (same system, same type of activity, technology involved, …). This simplification masks – in certain cases – variations in risk factors. kCHF V.Mertens – Consolidation activities for TE-ABT / “Consolidation Day” – 12.9.2013 6/8

8. Concluding remarks Delays to planned consolidation work are not a new phenomenon. For ABT this share of the activities has been since years the “buffer” to absorb other priority work (besides R&D, which got even more severely hit); that was communicated repeatedly. Again LS1 leaves less of the limited resources for consolidation than hoped – various reasons: more work, more difficulties to handle, planning “aléas” (waiting for support), … Due to the lack of more massive progress in consolidation the level of maintenance efforts during operational periods is substantially higher. It will lighten the management if “quasi-recurrent” work can be dealt with under exploi-tation, entailing a slight increase of that part of the budget (to be implemented if agreed). Having budget available is one necessary condition, planning for the manpower another one. One should firmly know 1-2 years in advance, which items will be done, and which time will be available to do the work (shutdown length) to plan best for consolidation activities in terms of resources and equipment preparation.
