• Four final drafts circulating (SRC, hypernuclear, E00-007, RCS cross section)
• Average time from completion of experiment to submission 20 months with 75% within 3
years.
• At present 5 experiments that have not submitted a manuscript more than 3 years after
completion
• Essential that more effort goes into publications, especially archival pubs

Budget consequences of continuing resolution not yet clear, can range from full restoration in FY07 of
appropriating committees’ budget (very optimistic) through restoration from moment budget is signed
to FY06 budget throughout FY07 (most probable, ~25% budget cut, not counting 12 GeV funding).
6 weeks further extension for G0 in March in addition to rescheduled running for Jan-Feb 2007
In Hall A highest priority to running experiments scheduled for 2007
Budget situation extremely tight at least until DOE budget has been resolved

• Work on the CM refurbishment and Renascence completion are now underway
• First refurbished CM to be installed as I speak and commissioned late February (four
months later than shown in figure)
• Committed to provide as close to 5.75 GeV as soon as possible, but consequences of FY07
budget as yet unclear

CD-1 approved on Feb 14, 2006
CD-2 “dry run review” ongoing
CD-2A review scheduled for summer of 2007, but could slip by a year
Goal was to achieve CD-2 baseline approval in 4QFY07
Kovar continues to express strong support for 12 GeV upgrade
Start of Machine Shut-down delayed until 2nd/3rd QFY13
CD-4 (project completion) delayed until 1QFY16
Conceptual design for solenoidal magnet has been initiated with the goal to
present it at the LRP Town Meeting, followed by strong support in the LRP
