  1. WWS Calorimetry R&D Review:CALICE Wrap-up Paul Dauncey, Imperial College London On behalf of the CALICE Collaboration LCWS R&D Review - Summary

  2. CALICE Summary • We believe an evaluation of different calorimeter technologies is essential to make the right choices • We believe this needs to be done in a systematic and coordinated manner • To provide meaningful comparisons • To make the most efficient use of scarce resources • We have planned a major program of R&D to achieve this aim • This is starting to produce results • First public presentations at this workshop • We estimate ~3 years to complete the full program • This will produce results in time for the detector EDRs LCWS R&D Review - Summary

  3. Schedule • Funding uncertainties make scheduling difficult but… • Physics prototypes beam tests • ECAL, AHCAL, TCMT: CERN Jul-Aug 2007 • ECAL, AHCAL, TCMT: FNAL Q1 2008 • ScECAL, AHCAL, TCMT: FNAL Q2 2008 • ECAL, DHCAL, TCMT: FNAL Q3 2008 onwards • Technical prototypes • ECAL, AHCAL: beam tests mid 2009-2010 • DHCAL: assembly and beam tests 2009-2010 • Analysis of data, understanding operational issues and incorporating results into detector optimisation will take time after the hardware programme is complete Mainly 2007/8 Mainly 2009/10 LCWS R&D Review - Summary

  4. Prototypes • The main issue is; can we achieve this schedule? • The CERN system is equivalent to an experiment in its own right • E.g. ECAL had more channels than BaBar’s; data rate was higher than H1 • We believe we have shown we have a critical mass of people • We ran continuous shifts with > 90% detector uptime throughout the run • We believe we have demonstrated we can deliver • Around 100M events have been taken and results are appearing LCWS R&D Review - Summary

  5. Management • We have a well-defined collaboration structure • Spokesperson (J.-C.Brient) • Steering Board (chair J.Repond): one member per country • Technical Board (chair J.Yu): subsystem leaders • Speakers Bureau (chair D.Ward): representatives from analysis groups • The collaboration has an MoU agreed by all institutes • There are regular technical reviews of the subsystems • There are regulations and guidelines for talks and (future) papers • There is a clear management structure in place • We believe we have demonstrated it to be working • We believe we have the expertise to direct the work • We can organise ourselves and know the issues intimately • With apologies to Churchill… Given the tools, we will finish the job LCWS R&D Review - Summary
