SVT Update
R&D work reorganized to prepare a baseline for TDR with:
Layer0 based on hybrid pixels:
Better chance (w.r.t to newer technologies) to meet the Layer0 requirements for the TDR timescale
50x50 mm2 pitch - first front-end chip & pixel sensor in production in Sept. ‘09.
R&D on pixel module support/cooling & interfaces (similar for all pixel options)
Layer1-Layer5 similar to BaBar SVT
Layer0 pixel options under study
Hybrid Pixels
CMOS DNW MAPS
Lower material & improved performance
Continue R&D on thin pixels technology
(SLIM5VIPIX Collaboration-INFN)
CMOS DNW MAPS + Vertical Integration technology very promising for Layer 0 but not yet mature for TDR timescale.
First DNW MAPS chip realized with two thin CMOS layers interconnected  first results by end of 2009
 if positive could be seriously considered for Layer0 performance improvement

26. Document describing ETD
The document describing the proposed architecture of the ETD system has been released last week:
It is the result of 3 months of continuous work, including numerous meetings with experts of the domain.
It defines the common electronics design:
Fast Control and Timing System (FCTS)
Control and readout links (Links)
Common Front-End Electronics (CFEE)
Hardware Trigger (L1T)
Read Out Module Boards (ROM)
Experiment control system (ECS)
It will be presented by D.Breton in the detector introductory session, and discussed in the ETD parallel sessions.
We hope to have fruitful discussions about it here this week.

Next steps
After the discussions which will take place during this workshop, the document will be upgraded to become the basis for the overall design.
It will also be the basis for the ETD section of the TDR.
Then we will be able to distribute the work between different teams.
Candidatures are welcome.
Don’t forget the L1 trigger ...
R&D has started concerning the links
A few presentations are foreseen about serializers embedded in FPGAs in the ETD parallel sessions.
But no easy solution emerged for the irradiated area, even if some good ideas have to be farther studied.
We have to estimate if the change in the machine characteristics won’t have too big consequences on our requirements.
