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.

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
