4. Focus on Previous EAC Endorsements

5. Focus on New Developments

6. Defining and Implementing an Initial Suite of Experiments & Scientific Roadmap • Some experiments being established  PICASSO prototyping Now (in SNO space)  DEAP-I to be installed this Fall (in SNO space)  SNO+ actively pursuing Funds & Collaboration • Updates & Schedules for Other Prospective Experiments Discussed Here  Requested brief status reports to accompany presentations • Some Uncertainties  Many projects in a stage of R&D … Is R&D / prototyping space required?  Many projects seeking funds  Prospects and schedule for DUSEL • Need to establish appropriate forum for technical review and implementation  Technical Research Proposals will be required • Need to establish overall scientific organization of the facility
