13. LIGO-G030557-00-M 3-June-04PAC Mtg -- Caltech13 AdLIGO Status as a Project Large Projects at NSF are funded through MREF account (projects with total cost of more than ~10% of the annual division budget) A long list of possible MREF projects (23) are under discussion by all the directorates and the list changes with time. A shorter list of reviewed projects (11) are discussed annually with the NSB annually (a more stable list, but not prioritized) The Assistant Directors advise the Directorate (who decides) what and when to bring projects forward to NSB for consideration and approval Next big step is to obtain NSB approval and then inclusion in future MREF budgets to OMB (FY06?)

16. LIGO-G030557-00-M 3-June-04PAC Mtg -- Caltech16 Site Plan OUTREACH CENTER LVEA OSB Existing unpaved site adjacent to LLO conference facility & temporary exhibit space Erect new building with direct access to auditorium foyer BUS & CAR PARKING staging lot

17. LIGO-G030557-00-M 3-June-04PAC Mtg -- Caltech17 Conclusions l S1 Analysis Complete. Five Papers approved for publication. l S2 Data Run was ~x10 better sensitivity and ~x4 more running time. Data analysis is near complete and we plan to present the results at GR-17 in Dublin in July. LSC Data Analysis Meeting this weekend l S3 Data Run: Three interferometers with extragalactic sensitivity. Analysis not yet underway l LIGO is shutdown to install L1 seismic mitigation l Advanced LIGO was proposed in Jan 03 and was well reviewed. It is now awaiting approval by the NSB. l Short term goals: »Commission Seismic Retrofit »Improve sensitivity and reliability to near design and initiate the extended LIGO I search run.
