3. IFAE Catania - E. Garutti3 Detector Concepts Concepts currently studies differ mainly in SIZE and aspect ratio Relevant: inner radius of ECAL: defines the overall scale LDC SiD GLD ECAL end-view Tracker SiD LDC GLD B = 5T B = 4T B = 3T Figure of merit (ECAL): Barrel: B R in 2 / R m effective Endcap: "B" Z 2 / R m effective R in : Inner radius of Barrel ECAL Z : Z of EC ECAL front face Different approaches SiD: B R in 2 LDC: B R in 2 GLD: B R in 2

16. 08/04/05Erika Garutti16 Test beam for VTX & Tracking VTX and Tracking group plans to put down requirements for beam tests –Less stringent beam requirement compared to CAL Broader facility options But still need to specify requirements –First requirements to be presented in Snowmass D. Bailey, H.E.Fisk

17. 08/04/05Erika Garutti17 Conclusion Wolfgang Lohmann (review of detector R&D): Its time to organize our community world wide to strengthen and structure the efforts in ILC Detector R&D Andy White (summary talk on Calorimetry): A vigorous program of LC calorimetry […] development is underway Many results from prototypes – but we should avoid too much duplication It is critical to carry out an R&D survey and ensure that Detector R&D proceeds in a timely manner alongside Accelerator R&D. Ji Yu (summary talk on Test Beams): Tremendous amount of activities Limited number of facilities for a combined calorimeter beam tests Fermilab is working closely with LC TB community WW coordination effort to pick up momentum Outlook: see you at LCWS06 !!!
