    12 GeV Upgrade

    Closeout reports with lessons learned are being developed for the Six-Month Shutdown in preparation for the next shutdown scheduled to begin in May 2012. The “Long Shutdown” planning team for JLab has been established. A range of 12 GeV installation activities will be incorporated into the labwide integrated installation schedule for the shutdown. Facilities Management & Logistics support is integrated with 12 GeV projects through the FM&L work order system and is coordinated weekly.
