Introduction

BI has around 2200 instruments on the
beamlines
of the LHC and injector chain
There are a number of issues that impact on their availability for operations:
lack of documentation,
obsolescence,
changing CERN environment and use (
eg
, vacuum, LHC wire scanner use)
Average time in storage is ~19 years
These can all be resolved, but we are limited by:
Budget, typically from the CERN consolidation project
People with the skills and availability to commit to this projectSlide4

Consolidation Budget and Plans

Initial requests from consolidation budget for ‘Critical Mechanical Spares’ for PS and SPS have been made and approved for the period 2014-2017
The following was already procured in 2014:
PSB BWS spare tank (corrosion issue)
PSB BWS replacement chamber
(
machine continuity)
PS FBCT spare ceramic chamber
Renovation of logistics and storage areas in B.865
The following is currently scheduled for 2015-16:PSB 2x spare wire scanner instrument assemblies (active spares to minimise intervention times)BTP line: BTV10 (replacement of unmaintainable instrument)PS SEM grids for PR.MSG48, PR.MSG52, PR.MSG54 (leaks in LS1 – unmaintainable)
SPS SEM SMG52SPS spare wire scanners, rotary and linear, numbers TBD (active spares to minimise intervention times)Sorting and re-validation of spares in radioactive storage
Further requests will be made for consolidation budgets in the future, limited as much by available manpower in BI as budgetFollowing recent LHC BWS issues, a consolidation budget will be requested for the LHCSlide8

Summary and Conclusions
9
We now have a good picture of the instruments installed in the injector chain
But we are missing many drawings, knowledge of spares and implementation of the logistics
This represents many man/years of work
The non-LHC chain is a significant new project, not currently resourced
We have a budget line and have started with the highest priorities from the risk list
Further input from OP and BI experts welcome to optimise this list
We will continue on this path to the limits of our resources for the coming period
… but this means that new spares or drawings will not be produced for instruments with a medium/low risk point score for some yearsSlide10
