  1. 12GeV Upgrade - Beam Transport Injection, Linac, Extraction, & Correctors Preliminary Design and Safety Review Extraction Michael Bevins May 17, 2007

  2. Outline • Introduction & Scope • Requirements & Specifications • New/Modified ExtractionElements/Girder Count • Beam Transport Layouts • Safety Considerations • Cost Estimates • Risk Assessment • Summary

  3. Introduction & Scope • The extraction region must be upgraded to support transport of higher energy beam to halls A, B, & C and 5th pass beam to the new arc 10 to support 12GeV operations • Songsheet level machine layouts will be presented along with cost estimates Extraction Region

  4. Requirements & Specifications • Alignment specs • Quads & dipoles positioned to +/-0.5mm in x & y, +/- 1.0mm in z • Vacuum specs • Beam line partial pressure of hydrogen <10-6 torr • Total average pressure of all other constituents less than 5x10-7 torr • Fabrication, welding, cleaning & handling, and leak checking specs still apply • 22631-S-001 Fabrication of Ultra-High Vacuum Equipment • 22632-S-001 Cleaning and Handling of U.H.V. Components • 22633-S-001 Welding Specification For U.H.V. Components • 22634-S-001 Helium Leak Test For U.H.V. Components • Note an update and modernization of our vacuum specs is underway

  5. New/Modified ExtractionElements/Girder Count • Preliminary - pending CASA review and more detailed vacuum study • Elements in red are part of I&C WBS

  6. Beam Transport Layout - Extraction

  7. Extraction Layouts – RF Separators Current Configuration 12GeV Configuration New double quad girder New quad girder Relocated New Two new pedestal stands Existing supports

  8. Extraction Layouts – RF Separators

  9. Extraction Layouts – Septa Magnet Stacks Current Configuration 12GeV Configuration New quad girder Two new support stands Relocated Two YBs One relocated and one new support stand New Three YRs Two new pedestal stands YA Septa Stacks YB/YR Septa Stack

  10. Extraction Layouts – Septa Magnet Stacks Existing YA Septa Stack Existing YB Septa Stack

  11. Extraction Layouts – Dipole Magnet Stacks Current Configuration 12GeV Configuration New Two new support stands Three BPs New BP Dipole Stack

  12. Extraction Layouts – Dipole Magnet Stacks Current Configuration 12GeV Configuration New

  13. Extraction Layouts – Dipole Magnet Stacks 12GeV Configuration Two existing BQs New support stand Three new BPs New New BP New pedestal for 5th pass BP downbeam support Two new pedestal supports for 5th pass BP BQ/BP Dipole Stack BP Dipole Stack

  14. Extraction Layouts – Dipole Magnet Stacks BP Stack BQ Stack Existing BQ Dipole Stack Existing BP Dipole Stack

  15. Safety Considerations • Personnel Training • Jlab & sub-contractor • Radiation • Designated areas for containment and radiation survey of material that will be removed from the tunnel • Material handling • Provide provisions for lifting • Electrical Hazards • Package and support electronics, power leads and terminal blocks to control electrical hazards

  16. Cost Estimates –Extraction WBS Rollup * * Septa and dipole vacuum chambers WBS Elements I have covered today

  17. Cost Estimates - Highlighted WBS Stands - Procurements

  18. Risk Assessment • Technical - Low • Girders & Supports – very similar designs exist and are already proven • Vacuum - existing designs already proven, detailed vacuum analysis TBD • Alignment - same as existing machine • Procurement Schedule - Low • No long-lead items identified • Cost – Low • Good cost estimates for machined parts • Vendor & Jlab shop budgetary estimates

  19. Summary • Preliminary extraction beam transport layouts and cost and installation estimates are complete based on present scope • We are in a good position to support our DOE External Project Reviews this summer • We will continue to work closely with our friends throughout the lab (safety, CASA, installation, vacuum, alignment, RadCon, I&C, magnet measurement, operations, procurement & facilities) as we move forward • Detailed design will be completed to support assembly and installation schedules • We look forward to comments & recommendations from the committee
