1 1 May 10, 2007 Detector group organization For the CDR writing we had identified subsystem editors/conveners This structure has concluded its function Many thanks for the effort and commitment We should move forward to the next phase Goals: Advance the R&D activity as coherently as possible Start creating the infrastructure and doing the work needed for a Technical Design Report Prepare the ground for the formation of a collaboration We need to keep a delicate but essential balance: Move forward coherently Leave room for other groups to join Dal CDR al TDR, occorre una Collaborazione

2 2 May 10, 2007 R&D Perspectives R&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 issues Avoid duplication of effort Act together to ask for money Provide a structure for new activities or new groups INFN comincera a finanziare nel 2008

3 3 May 10, 2007 R&D Coordination I think it would be useful to setup a structure of R&D conveners for the subsystems with the job of: Keep track/coordinate activities Help groups focus on what is needed Provide a point of reference for groups or individuals wishing to participate Help prepare funding proposals or reports Each subsystem should have one or two conveners Lets use the rest of this workshop to discuss about names Not all the vacancies need to be filled now Not a life sentence: which should allow dynamic adaptation as things evolve Considerazioni (quasi ovvie) al contorno

4 4 May 10, 2007 Subsystems MDI (including beam pipe) SVT (including Layer0) DCH EMC (including endcaps)(**) PID (including endcaps)(*) IFR (**) Electronics Trigger/DAQ Computing Software Shopping list, * indica possibile interesse nostro

5 5 May 10, 2007 R&D Review and choices At some point we will need a more formal R&D review process Committee to review and monitor activity and provide advice to the management IMHO this should be setup when the collaboration is formed or forming For some regions it may be advantageous to create this committee earlier We need to explore the ramifications of this proposal Eventually we will have to make choices about technology Usual difficult balance between good that works and better that might not We should use the time in front of us to develop the new technologies as much as possible Act together as a group working towards an experiment Minimize pain and disappointment when choices will actually be made by the SuperB collaboration Ulteriori considerazioni

6 6 May 10, 2007 Software Simulation We need to ramp up our simulation ability More and more detailed Connection with physics group and accelerator design Physics studies Background simulation Detector studies Infrastructure We need to start setting up a software infrastructure (and group) From repository to framework Weve been using SLAC/Babar so far. How much longer ? Questo riguarda tutti, quindi anche noi!

7 7 May 10, 2007 Last but not least Infrastructure in Tor Vergata We need to proceed with a feasability study for the Tor Vergata site It is essential to define building volumes and functions Experimental hall(s), support buildings and caverns, shafts, assembly halls, … We have regular meetings with the Tor Vergata engineers and architects Need input and answers from the Accelerator and Detector group Questo non ci riguarda da vicino, ma e vicino!!!!

8 8 May 10, 2007 PID Three active groups: SLAC, Ljubljana, BINP DIRC Barrel readout Forward (Backward PID): TOF, Focusing RICH Ratcliff Projected performance Per gli amanti della photon detection

9 9 May 10, 2007 Forward PID Physics case Cost/benefit analysis Technology choice/maturity TOF resolution Bench 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. Ratcliff Križan

10 10 May 10, 2007 Forward PID MCP PMT development in BINP Photocathode ageing is rate dependent Counting rate was increased from test to test keeping the integrated cathode charge constant ( ~5 nC) 3 MCP PMTs have the same life time as 2 MCP with protective layer Kravchenko Križan

11 11 May 10, 2007 EMC Active group in CALTECH (Ren-yuan Zhu) Hitlin Interessa anche PG, PD, sinergia con CMS-Roma

12 12 May 10, 2007 Acceptance studies B benchmark Basis for a cost benefit analysis of a backward calorimeter Need to commission a full detailed study for the TDR Forw acc. Backw. acc. BKGD/Signal with smearing BKGD/Signal with smearing Mazur

13 13 May 10, 2007 IFR For the scintillator we are in 2002 (virtually) No active group (yet) Need to get going if we want to be ready in time Cavoto R&D NOW (TO DO) Sinergia con Cuore (+Pd, Fe)
