Georg's slides summarising the ATLAS and ATLAS upgrade experience are at https://agenda.linearcollider.org/event/6656/contribution/1/material/slides/1.pdf
His conclusions are that the ATLAS tracker is essentially stable at the 1-2 micron level, apart from occasional "seismic" events (magnet quenches, cooling system interventions etc), and that the alignment can be done extremely well with tracks within these periods. Hardware alignment systems and even initial surveys have been of secondary importance. It is therefore essential to have alignment experts and mechanical engineers working together from the earliest design stages.
There was considerable discussion, including how much of this will change at the ILC: the number of tracks, required alignment precision, vibration environment due to pulsed power and relative alignment to other detector elements will all need careful consideration.
There was a discussion on whether to continue holding virtual meetings every four weeks or so, whether or not this time slot should be used, or whether we should make an effort to meet in person. It was agreed to continue this offline.
Konstantin's slides are at https://agenda.linearcollider.org/event/6656/contribution/4/material/slides/0.pdf although as several people had to leave at 1:30 he only had time to reach slide 8. The presentation and discussion will resume next time.
