A Final Word

A Final Word

• MDI _at_ ILCJan 8th, 2005
• Eric Torrence
• University of Oregon

2
Words of Thanks

• To the attendees, who made it on short notice
• To the session organizers
• To the local organizing committee Markiewicz,
  Seryi, Woods
• Naomi Nagahashi

Purpose of MDI
Machine
Detector
Physics
Complicated Optimization with many
parameters Need to expand knowledge beyond one
particular box
4
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

5
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

6
Design Progress

• Significant progress in last six months
• Real progress on strawman since KEK

7
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

8
MDI Communication

• 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

9
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,

Timeline
1st ILCMeeting
MDI Workshop
BDIR Workshop
Snowmass
LCWS
You AreHere

• 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

11
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

12
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
