Minutes Meeting 12/2/26

Attendees: Roman Pöschl, Andy White, Frank Gaede, Karsten Buesser, Aidan Robson, Daniel Jeans, Timothy Barklow, Graham Wilson,  Mary-Cruz Fouz Iglesias, Jenny List

  • Roman presented first proposal of workplan including the estimated work force
  • FTE should be rather interpreted as number of persons -> Will change document /workplan to be more precise 
    • 10 involved persons for one concept is overall still a reasonable estimation
  • Karsten pointed out the importance on the actual integration in terms of civil engineering
    • team of engineer and physicist -> Coordinate with team at CERN 
  • It was pointed out that a larger L* gives more freedom for the detector design (e.g. longer tracking system) 
    • A study may have an interest to exploit the advantages of a larger L* -> however major redesign 
  • The idea to focus on a study for one concept was for practical purposes overall considered the right way (but the discussion did not close the door to individual studies)
    • ILD will most likely launch a study at 25 mrad crossing angle 
    • SiD will survey what can be done with the existing work force but also under the constraints set by DOE to focus on FCC
    • CLICdet at this moment does not consider to launch a study 
  • The concepts are asked to assess the situation on their possible involvement, feedback should be collected until March 13th, 
    • in any case we should avoid double work 
  • The meeting ended with a discussion on how to keep e.g. the \gamma\gamma option on board. Studies on which crossing angle can be tolerated are ongoing
    • Since it is still likely that \gamma\gamma will prefer smaller crossing angles one may study this option in more detail, if work force permits 
    • Would clearly demonstrate clearer the versatility of LCF.
  • Karsten pointed out that the infrastructure should be able to cope with multi-TeV e+e- beams
