1. TPC Performance goals. RD question:• How was the subdetector

optimized?

• ILD subdetectors must be optimized coherently by present optimization studies, for the TPC, this means:

Inner Detectors back to Machine since this is complicated real-estate where MDI, machine and detector elements are critical…

FD Cryostats

Working progressJohn Amann, et al

Each part of FD cryostats will have movers to align Cryostats as a whole(?),And support parts of FD

Cryostats may need to be equipped with optical or

mechanical lock-in systems, to minimize their relative

motion on nm level.

Combination of detector and machine elements.“Detector view of MDI”? Nanobeam02 paper…

Many very correlated tasks!!


2121

In preparing this talk, I noticed the different ways to categorize…

Nanobeam 02 paper:

Karsten Buesser CLIC talk:

vibration, optics, instrumentatn,background, engineering

Andrei Seryi IRENG07: Yasuhiro Sugimoto, Toshiaki

Tauchi, Karsten Buesser et al ILD MDI/Integration list:

1. IR issues/tasks

2. Detector Integration tasks

3. Push-pull issues/tasks

Many subitems under each point, my favorite brkdown


2222

•Vibration—det&hall design to avoid unwanted (μm-mm!) vibrations

•Optics—machine, BDS design/layout (details in Andrei’s and Toshiaki’s talks today)

•Instrumentation/diagnostics—fast feedback,beamcal e.g.

•Background—beam induced bgrd,inner detector design

•Engineering—

•Detector design/integration

•MDI magnets (antiDID)

•IR hall/push-pull design (Andrei’s talk today)

•Shielding

•Etc…

Combining MDI/Integration makes a lot of sense, as the IRENG07 workshop, the ILD task list and Andrei’s/Toshiaki’s lists today show, maybe something like:

LOI, remaining points…

Conclusion?

No conclusion…
