12 GeV Upgrade
Installation work in Hall B is very busy and presents many overhead hazards. Detector work is proceeding with the cabling of the Low Threshold Cerenkov Counter. Torus magnet activities include installation of the cabling raceways as well as additional infrastructure and support services, such as Low Conductivity Water, electrical, cryogenic piping and gas systems. With all of these overhead activities, it is important that precautions be taken to prevent tools and equipment from falling. Examples of solutions that will reduce risk are to tether tooling when possible, organize and safely store/transport tools and materials, and maintain good housekeeping in your work area.

The phenomenological success of the systematic application of chiral effective field theory (χEFT) to the electromagnetic and weak observables of light nuclei has been remarkable. In a recent review article, the background and early application of chiral Lagrangians to nuclear current operators, and G.E. Brown's role as an initiator of this approach, are reviewed. A summary of the current status of nuclear χEFT and a set of illustrative examples of its application to electroweak observables are also provided.
The installation group has completed many tasks to support the Hall C Dump upgrade, including:
Additionally, the Installation group installed cable trays for the Upgrade Injector Test Facility, acid flushed arc box supplies and fabricated hoses for Hall B Torus power supply leads.
The Vacuum group has completed the Hall C beamline at the cantilevered stand and bridge section, including adding a foil target at the end of the superharp girder to support the upcoming four-day run. They have also handled the purchase and assembly of the Hall B Torus vac system and completed assembly/installation of the tune mode viewer and calibration puck assemblies for the Hall C dump vac tube. Vacuum continues to support CEBAF during the current run.
Both groups supported a quick turn removal/re-installation of the East Arc Dipole MJC5A14 from CEBAF.
