  1. 1 Linac4 Status – July 2012 Project Meeting 12.07.2012

  2. Somerecentviews (16.5.2012)

  3. Linac tunnel - 2012

  4. Ion source and RFQ Production of the new H- source is progressing, to be installed soon in the 3 MeV test stand Radio Frequency Quadrupole (RFQ): Last segment (#2) successfully brazed Assembly of complete RFQ week of 16.7 RF measurements week of 23.7

  5. Financial situation - 2012 • Total 2012 budget (CET): 25.9 MCHF • Paidat 9.7.12: 5.5 MCHF • Paid + Committedat 9.7.12: 19.9 MCHF • High level of committments: HP-RF (4.9M), PIMS (1.3M), CV (1.5M), magnets (1M), EL (0.6M), DTL (0.6M) + others. Comittmentsshouldbemoved to 2013 for items not to bedelivered in 2012.

  6. Financial - BE From Alan Burns presentationat BEMB 9.7.12

  7. Project status – from EVM Linac4 global green: AC yellow: EV 50M/90M=56% of project Somedelayw.r.t. original plan Good agreement betweenearned value and actualcost, but severaldiscrepanciesat WP level

  8. Linac and infrastructure Linac machine overspending by 2M (includes components paidbeforeearning the value…) Infrastructure (CE,CV,EL) underspending by 2M (includesservices where the value isearnedbefore the bill ispaid…).

  16. The Linac4 Safety File(s) the project phases 2004 2008 2014/2016 2046? STUDY PROJECT EXECUTION OPERATION DISMANTLING UPGRADE ? Linac4 Safety File (EDMS 905423) June 2008, 91 pages All safety aspects of project, more emphases on civil engineering and machine equipment New Linac4 Safety Folder In preparation by Anne Funken All safety aspects of project, more emphasis on operation. Update of existingSafety File, document followingrecent CERN safety documentation standard (EDMS1177755, 15.6.2012). Approval for tendering of building and execution phase Linac4 Decommissioning Report In preparation (deadline end 2012) Calculation of activation at end of life Estimate of materialquantities for disposal Estimate of the costs (for financial reports) Approval for operation above 3 MeV energy (2014)

  17. Linac4 Safety Folder • The referential in matters of safety for Linac4 is the Safety File which dates back to 2008, https://edms.cern.ch/document/905423/1 • The update of this document is in progress to integrate the changes which occurred and detail subjects which were not yet defined: • Interlocked areas and EIS • Dumps • Ion source changes • At the same time, the contents of the document is reorganized according to the new “Quality Procedure for Safety Documentation Management”, https://edms.cern.ch/document/1177755/0.2 • The safety folder is composed of 4 main safety files (separate documents) : • Descriptive part • Demonstrative part (Risk Control Measures) • Operational part • REM part (Records, Experience, Monitoring)

  18. Descriptive part - progress

  19. Editorial work progress • Risk control measures regarding high voltage and RF power of the ion source, EDMS 1212106

  20. Operational part • Content : list of the safety-related and operational procedures with the links to the documents • Deadline : • These procedures shall be prepared and approved prior to the commissioning and operation phases • For the ion source: the deadline is October 2012

  23. Linac4 Safety structure • The Project Leader is responsible for Safety in the Project (hecanbeassisted by a PSO). • WorkPackages are responsible for Safety within their WP (and follow the standard safety line Group –- Department assisted by DSO). • The Project provides the global view and the time perspective: • Coordinates safety issues at the interfaces between WPs (transfer of information, coactivity, etc.) • Verifies that Safety issues are correctly considered within the individual WPs. • Directs safety issues in the sense of a minimisation of risks for all the different phases of the project. • From SAPOCO 4.8: Project Leaders are responsible for Safety in their project. They must ensure that all Safety requirements have been taken into account from the design stage and subsequently at all stages of their project’s development through to its dismantling and final disposal.

  24. Linac4 HazardInventory Strategy for radiation protection (seenextslides) Radio Frequency (352 MHz, standard precautions) Standard at CERN Caesium for ion source, specificprocedures Standard at CERN

  25. Upgrade of measurementlines Upgrade of the beammeasurementlinesat the entrance of PS Booster: - Upgrade for 160 MeV energy (new magneticelements and new measurement technique); - Introduction of appropriatebeam dumps to beusedduringmeasurements
