Inner Tracking/Vertex DetectionDetector RequirementsDetector Requirements

Excellent space point precision ( < 4 s )

Superb impact parameter resolution ( 5µm 10µm/(p sin3/2) )

Transparency ( ~0.1% X0 per layer / 4-5 layers)

Track reconstruction ( find tracks in VXD alone )

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

ConclusionWolfgang 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 !!!
