Thomas Jefferson National Accelerator Facility R.. McKeown Page 5 12 GeV Approved Experiments by PAC Days More than 7 years of approved experiments

Thomas Jefferson National Accelerator Facility R.. McKeown Page 6 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

Thomas Jefferson National Accelerator Facility R.. McKeown Page 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

Thomas Jefferson National Accelerator Facility R.. McKeown Page 8 Future Projects Super BigBite Spectrometer (Approved for FY13-15 construction) - high Q 2 form factors - SIDIS MOLLER experiment (MIE – FY14-18?) - Standard Model Test SoLID (SIDIS, PVDIS) Chinese collaboration CLEO Solenoid? Directors review:

Thomas Jefferson National Accelerator Facility R.. McKeown Page 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  0 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).

Thomas Jefferson National Accelerator Facility R.. McKeown Page 10 Status: A’ Experiments APEX - completed test run (published) - awaiting radiation impact review, $$ HPS - completed parasitic test run, now C1 - review results, promote C1  Approval? - HEP funding… DarkLIGHT - completed test run at FEL - held briefing Oct. 22 for approval – more HW due - HEP/NP funding?

Thomas Jefferson National Accelerator Facility R.. McKeown Page 15 Electron Ion Collider 15 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?
