1. What’s Falling Apart in the Injector Chain ? PS/SPS Days January 2005

2. PS/SPS Consolidation, J. Poole, January 2005 1 Consolidation When equipment and facilities are built they have an expected lifetime which should be reached if they are maintained properly and used in the correct way. Extension of the lifetime beyond this expected value requires renovation/modification/replacement i.e. consolidation It is generally accepted that an annual investment of >2% of the capital cost of an installation is required for consolidation – PS and SPS cost approximately 1BCHF therefore we should invest ~20MCHF p.a.

3. PS/SPS Consolidation, J. Poole, January 2005 2 Methodology If the cost of a proposed consolidation activity is <100kCHF, it is not accepted in the consolidation project and it has to be paid from the Group’s exploitation budget. A risk analysis of systems proposed for consolidation has been made. This will be reviewed at regular intervals because new activities are arriving all of the time and equipment continues aging and the probability of failure will increase. Activities are ranked according to risk score (and some fine tuning). The cut is made according to the ranking and where costs match funding.

4. PS/SPS Consolidation, J. Poole, January 2005 3 Risk Analysis The Risk Score is evaluated as the product of the probability of failure of the equipment and the impact that it will have. Probability of failure Rare (less than once in 25 yr) – probability <0.1 Score 1 Possible (once in 5 to 10 yr) – probability 0.2 to 0.5Score 2 Likely (once in 2 to 5 yr) – probability 0.6Score 3 Frequent (once per year or more) – probability 0.9Score 4

5. PS/SPS Consolidation, J. Poole, January 2005 4 Impact Impact on CERN’s Scientific Objectives I o Insignificant – loss of one day of physics or less Score 1 Moderate – between 1 day and 1 week loss of physicsScore 2 Major – up to a few (3 to 5) weeks loss of physics Score 3 Catastrophic – operation stops, fail to meet scientific objectivesScore 4 Impact on CERN/AB’s Reputation I R Insignificant Score 1 Moderate – problem dealt with at Department levelScore 2 Major – problem dealt with at Executive Board or Council/FCScore 3

6. PS/SPS Consolidation, J. Poole, January 2005 5 Other Impacts Financial Impact I F Insignificant – less than 0.5% of AB annual budget (<120kCHF)Score 1 Moderate – 1– 4% of AB annual budget (.25 – 1.0 MCHF)Score 2 Major – additional budget required Score 3 Catastrophic – report to Council/FC, CERN’s future jeopardisedScore 4 Safety Impact I S Insignificant – no injury or environmental impact (like pollution or radiation exposureScore 1 Moderate – require medical attention, no loss of working timeScore 2 Major – extensive injury, loss of working daysScore 3 Catastrophic – loss of lifeScore 5 Mandatory safety or regulatory requirementScore X

16. PS/SPS Consolidation, J. Poole, January 2005 15 Situation in 2005 AD consolidation has not been taken into account yet. Groups are submitting new data (and increasing their estimates of P+M). If all of the activities above the cut off are started, we would need 11MCHF in 2005, plus a loan on the exploitation budget to cover the non-consolidation activities (loan of ~2.24MCHF needed in 2005). These issues are currently under discussion and the detailed planning for the consolidation activities will be defined with the Group Leaders in the coming weeks.
