Detector group organizationFor the CDR writing we had identified subsystem editors/convenersThis structure has concluded its functionMany thanks for the effort and commitmentWe should move forward to the next phaseGoals:Advance the R&D activity as coherently as possibleStart creating the infrastructure and doing the work needed for a Technical Design ReportPrepare the ground for the formation of a collaborationWe need to keep a delicate but essential balance:Move forward coherentlyLeave room for other groups to joinDal CDR al TDR , occorre una Collaborazione

R&D PerspectivesR&D will be funded at the local or regional level until there is a SuperB collaboration.Groups approach(ed) their funding agencies to get support for what theyre interested in.Nonetheless now that we have a CDR detector, coordination of activities is important:Identify the most important R&D issuesAvoid duplication of effortAct together to ask for moneyProvide a structure for new activities or new groups

INFN comincera a finanziare nel 2008

R&D CoordinationI think it would be useful to setup a structure of R&D conveners for the subsystems with the job of:Keep track/coordinate activitiesHelp groups focus on what is needed Provide a point of reference for groups or individuals wishing to participateHelp prepare funding proposals or reportsEach subsystem should have one or two convenersLets use the rest of this workshop to discuss about namesNot all the vacancies need to be filled nowNot a life sentence: which should allow dynamic adaptation as things evolveConsiderazioni (quasi ovvie) al contorno

R&D Review and choicesAt some point we will need a more formal R&D review processCommittee to review and monitor activity and provide advice to the managementIMHO this should be setup when the collaboration is formed or formingFor some regions it may be advantageous to create this committee earlierWe need to explore the ramifications of this proposalEventually we will have to make choices about technologyUsual difficult balance between good that works and better that might notWe should use the time in front of us to develop the new technologies as much as possibleAct together as a group working towards an experimentMinimize pain and disappointment when choices will actually be made by the SuperB collaborationUlteriori considerazioni

SoftwareSimulationWe need to ramp up our simulation abilityMore and more detailedConnection with physics group and accelerator design Physics studiesBackground simulationDetector studiesInfrastructureWe need to start setting up a software infrastructure (and group)From repository to frameworkWeve been using SLAC/Babar so far. How much longer ?Questo riguarda tutti, quindi anche noi!

Last but not leastInfrastructure in Tor VergataWe need to proceed with a feasability study for the Tor Vergata siteIt is essential to define building volumes and functionsExperimental hall(s), support buildings and caverns, shafts, assembly halls, We have regular meetings with the Tor Vergata engineers and architectsNeed input and answers from the Accelerator and Detector group

Questo non ci riguarda da vicino, ma e vicino!!!!

Forward PIDPhysics caseCost/benefit analysisTechnology choice/maturityBench tests of fast timing PMTs are encouraging to date. Best results with the laser diode:- s ~ 12 ps for Npe = 50-60 (as expected from 1cm thick Cherenkov radiator).- s TTS < 26 ps for Npe ~ 1.- Upper limit on the MCP-PMT contribution: s MCP-PMT < 6.5 ps.- TAC/ADC contribution to timing: s TAC_ADC < 3.2 ps.- Total electronics contribution at present: s Total_electronics~ 7.2 ps.

More to come soon.We plan to continue detector work and confirm TOF performance in a test beam run this year.However, test beams at SLAC after this year are a concern.
