Proposal for Backlog Management
Re-evaluate Priorities Timing 2015 Charge
select high impact experiments for 3
years (beyond commissioning)

• Nominally consider about 300 pac-days per hall
• Start with A rated approved experiments
• ( selected others?)
• Equip. availability input from Hall Leaders

7
Other PAC Issues

• New charge (no longer top ½ of first 5 years)
• Reconsider proposal process for Hall B (parallel
  running) possible impact on other halls (e.g.,
  SoLID, Hall D)
• New categories for resource availability
• - Stage I resources need to be
  identified/obtained
• - Stage II resources are essentially available

8
Future Projects

• Super BigBite Spectrometer
• (Approved for FY13-15 construction)
• - high Q2 form factors
• - SIDIS
• MOLLER experiment
• (MIE FY14-18?)
• - Standard Model Test
• SoLID (SIDIS, PVDIS)
• Chinese collaboration
• CLEO Solenoid?
• Directors review 2012-3

9
Other Projects/Upgrades

• Windowless target for proton charge radius
  experiment (NSF/MRI)
• Hall B (CLAS12)
• -Forward tagger (NSF/MRI INFN)
• - planning for one-sector RICH for Hall B
• - Micromegas for CLAS12 (IRFU agreement)
• Backward-nucleon detector (Israel) and planning
  for p0 spectrometer in Hall C
• Planning for Cherenkov and FCAL upgrade in Hall D

These are upgrades/enhancements to 12 GeV
projects, still under development (various
degrees).

Electron Ion Collider
NSAC 2007 Long-Range Plan An Electron-Ion
Collider (EIC) with polarized beams has been
embraced by the U.S. nuclear science community as
embodying the vision for reaching the next QCD
frontier. EIC would provide unique capabilities
for the study of QCD well beyond those available
at existing facilities worldwide and
complementary to those planned for the next
generation of accelerators in Europe and Asia.

• White Paper developed by JLab/BNL communities,
  posted for comment
• JLab MEIC design well-developed, design report
  posted
• Next NSAC Long Range Plan?

Medium Energy EIC_at_JLab

• JLab Concept
• Initial configuration (MEIC)
• 3-11 GeV on 20-100 GeV ep/eA collider
• fully-polarized, longitudinal and transverse
• luminosity up to few x 1034 e-nucleons cm-2 s-1
• Upgradable to higher energies (250 GeV protons)
