Purpose of MDI
Machine
Detector
Physics
Complicated Optimization with many parameters
Need to expand knowledge beyond one particular box
Current MDI Goals

Identify hard constraints

Understand comparative advantage of parameter
variations

Work towards complete conceptual design

Do not try to prejudge the final design
Strawman BDIR



Need more than quick studies
Must start designing something concrete to
understand consequences of certain decisions
Two angles needed to explore parameter range
Design Progress
Significant progress in last six months
 Real progress on strawman since KEK

Physics/Detector Communication


Maintain contact with detector/physics groups
 Important part of optimization process
 Detailed studies often slow
Communication at various levels
 Reports at detector concept meetings
 LCWS
 Directly with WG conveners
 Regional subsystem meetings
Propose specific questions, tasks
MDI Communication
QuickTime™ and a
TIFF (LZW) decompressor
are needed to see this picture.




Real work is done locally
Important to establish good inter-regional
communication
Workshops only go so far
Strongly support some mailing list/forum/hypernews
communication channel
Testbeams
Some questions only answered with data
 Long lead times - must identify early
 Limited resources and facilities
Try to coordinate globally

Ex: ESA energy program, BPMs at ATF,
Forward Detectors, …

You Are
Here



LCWS - 18-22 March, Stanford
BDIR Workshop (WG4) - 20-23 June, RHUL
Snowmass - 13-27 August, Colorado
“CDR” by end of the year?
We must be ready for that possibility
Goals from Snowmass
Conceptual design largely complete
 Matrix of parameters and relative
merits/impacts filled in
 Identify (few) remaining questions to
answer by end of 2005
 Tie up loose ends before CDR

In Conclusion

Good progress toward conceptual design

MDI needs to maintain good
communication as designs (machine and
detector) become more concrete

Lets get back to work…
