  14. DOE Generic Project Timeline We are here MAR 2004 FEB 2006 NOV 2007 SEP 2008 12 GeV Upgrade – Approval dates

  15. DOE Critical Decision Schedule CD-4 split in two to ease transition into operations phase (A) = Actual Approval Date

  16. 12 GeV Schedule • May ’11 - Oct ‘11 6-month “down” for initial installations • Nov ’11 - May ‘12 6-month run 6GeV • Jun ’12 - May ‘13: 1-year “down” for major installation • June ’13 - Sep ‘13: Accelerator commissioning

  17. 12 GeV Schedule • Oct ‘13: Hall A commissioning start • Apr ‘14: Hall D commissioning start • Oct ‘14: Hall B & C commissioning start

  18. 12 GeV Upgrade: Phases and Schedule (based on funding guidance provided by DOE-NP in June-2007) • 2004-2005 Conceptual Design (CDR) - finished • 2004-2008 Research and Development (R&D) – finished (but 1 task) • 2006 Advanced Conceptual Design (ACD) - finished • 2006-2009 Project Engineering & Design (PED) - ongoing • 2009-2014 Construction – started !! • Parasitic machine shutdown May 2011 through Oct. 2011 • Accelerator shutdown start mid-May 2012 • Accelerator commissioning start mid-May 2013 • 2013-2015 Pre-Ops (beam commissioning) • Hall A commissioning start October 2013 • Hall D commissioning start April 2014 • Halls B and C commissioning start October 2014

  19. 12 GeV Major Procurement Effort • Of the 29 Advanced Procurement Plans, 22 major procurements are being actively worked (~$65M Phased). A summary of their status is as follows: • 3 Requests for information completed • 3 Specifications completed • 4 Open Solicitations (including CLAS12 Solenoid) • 8 Bids Received (including CLAS12 TORUS) • 1 Vendor Selected (Hall D Civil Construction Manager) • 3Awarded (Hall D B-Cal Fiber, CHL Civil, Hall D Civil) • 22 Active Major Procurements

  20. Future Upgrades to CLAS12 Base Equipment • Micromegas (Saclay) • Detailed simulation and track reconstruction • Prototypes being tested, engineering design underway • Review will take place in May 2009 • RICH Detector (INFN, Argonne, UK ) • Conceptual design with detailed simulations • PAC 34 approved 3 major experiments requiring RICH • Neutron detector (IN2P3/INFN) • Detailed simulations, components being studied • PAC 34 gave high rating to the science presented in LOI • HD-ice Polarized target (JLab/INFN) • Laboratory facility being designed • Quasi real photon tagging facility (INFN, UK) • Feasibility study

  21. 2007 NSAC Long Range Plan (4 recommendations) Recommendation 1 We recommend the completion of the 12 GeV Upgrade at Jefferson Lab. - It will enable three-dimensional imaging of the nucleon, revealing hidden aspects of its internal dynamics. • It will complete our understanding of the transition between the hadronic and quark/gluon descriptions of nuclei. • It will test definitively the existence of exotic hadrons, long-predicted by QCD as arising from quark confinement. • It will provide low-energy probes of physics beyond the Standard Model complementing anticipated measurements at the highest accessible energy scales.

  22. Message from JLab Director to CLAS12 Workshop I had hoped to be with you for at least part of the workshop; unfortunately it became necessary for me to attend a conflicting meeting in Washington, DC, so although I believe my name appears in the participant list, I can claim only a virtual presence. …. you can be assured that we are working hard to provide the resources both for the 12 GeV Upgrade project and for the running of the 6 GeV program. We were very pleased that recently we received 19 proposals for experiments in the 12 GeV era including some which seek to extend the scope of the currently planned equipment. ….. it is very important that we ensure the resources to provide the base capabilities, but it is also important to develop initiatives and momentum which will ensure an expanding program as we start to operate the machine in the new era. Please convey my best wishes to all, and, especially to the collaboration, my hopes for a successful workshop. Hugh Montgomery

  23. Summary • The 12 GeV Upgrade is the NSAC #1 Recommendation • The 12 GeV Upgrade is the highest priority at Jefferson Lab • The project is in construction phase: CLAS12 construction started with the first major procurements in progress: the superconducting magnets, the forward tracking detectors, and the pre-shower calorimeter. This is a very exciting time for hadronic physics, and the perfect time for new collaborators to make significant contributions to the physics and equipment of CLAS12

  24. 12 GeV Upgrade Summary • R&D is essentially complete • PED (Engineering Design) finishes this year (18% remaining) • Construction has started ! • Significant progress: • Procurement planning and awards • MOU development • Installation planning • Space planning • Last 6 months – very exciting! • Next 6 months – lots of hard work ahead • Continued strong User participation is critical to success

  25. CLAS12– Central Detector • Charged particle tracking in 5T field • ΔT < 60psec in CTOF for particle id • Vertex reconstruction • Moller shield • Polarized target operation ΔB/B < 10-4 • in 3x5 cm cylinder around center Extension may include • Central Tracking w/ Micromegas • Neutron Detector • Bonus detector
