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) 3 Awarded (Hall D B-Cal Fiber, CHL
Civil, Hall D Civil) 22 Active Major Procurements

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

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
