Hall A Installation Review John J. LeRose 2/25/2009

“Installation” work for 12GeV in Hall A Arc dipole calibration extension Møller upgrade to handle 11 GeV Beam Compton upgrade to handle 11 GeV Beam

Thomas Jefferson National Accelerator Facility Page 3 Leave the magnets and mapper alone Just upgrade the arc dipole magnets power supply Cross calibrate 8 arc dipoles and the 9 th using the unmodified mapper* * WBS BEAMLINE - ARC Energy Measurement

Thomas Jefferson National Accelerator Facility Page 4 Add quadrupole Q1’ New field-exclusion insert Raise detector by 100 mm WBS BEAMLINE - Møller Polarimeter

Thomas Jefferson National Accelerator Facility Page 5 11 GeV upgrade builds on 6 GeV changes (infrared to green laser) Raise D2, Optical Cavity, Photon Detector, & D3 by 82 mm Rebuild vacuum line Add motion mechanism to electron detector WBS BEAMLINE - Compton Polarimeter Done
