4. GEn_stat_12-05 Hall A Collaboration Meeting December 5-6, 2005 Neutron Arm Combined weight of modules and shielding ~83 tons

5. GEn_stat_12-05 Hall A Collaboration Meeting December 5-6, 2005 Polarized 3 HeTarget Using new hybrid cells 7-8 working cells in-hand 4 cells P 50% in the lab (53% max) Short spin-up time implies reduction of P by beam will be small

6. GEn_stat_12-05 Hall A Collaboration Meeting December 5-6, 2005 Project Milestones Nov 15 -- completion of ND testing -done Nov 18 -- laser safety review -done Nov 28 -- first day of down, completion of ND testing, begin decabling. –done Dec 5 – Begin moving BigBite detector package, electronics, and cables (on track) Dec 15 -- full safety review for GEn (include beamline testing with conclusion of rupture tests) (Committee selected and scheduled for December ?) Dec 15 -- target motion system working on test bench Dec 15-- septum off pivot, begin moving neutron arm Jan 2 -- target testing complete, dissassemble target, ready to move into the Hall Jan 16 -- install Big Bite stand Jan 27 -- operational checkout of polarized target Feb 9 -- Big Bite operational checkout Feb 15 -- target button up Feb 17 – Laser safety inspection Feb 22 -- neutron arm complete with shielding

8. GEn_stat_12-05 Hall A Collaboration Meeting December 5-6, 2005 Outlook Detector testing and installation are on-track Expected beam and target polarizations are better than anticipated in the original proposal (86% and 50% vs. 75% and 40%) Much work remains, any and all help will be greatly appreciated Its not too soon to signup for shifts
