Hello Anyes,

Looks good.  A few suggestions:

-sl 4: the title doesn’t really match the slide.  Maybe change to “ATLAS Muon System”?

-sl 5: Please indicate where the MDTs are - you have everything labeled in the figure except the MDTs; the bottom figure labels are unreadable.

-sl 8: UM could be many things, so expand a bit (maybe also UCI => UC Irvine)

-sl 11: external dependencies for 6.6.3…

-sl 13: maybe start with “All chambers built and shipped to CERN”; Missing “year” at the very end of the slide

-sl 14: please change commissioning to integration; either 2 BIS1 or 4 …

-sl 16: define VS

-sl 17: what do you mean by “risk mitigation before launching pre-prod”?  Define MDTTP (or maybe better don’t use it, just say L0MDT)

-sl 26: for the TDC you don’t say what you did with the risks listed

-sl 27: the 255/241 is for CSM, not L0MDT!!  (See the spreadsheet we sent.)  This may also invalidate your statement on the previous slide about main remaining risks…

-sl 34: deliverable*s* leverage; the 241 is for CSM, see above; progress has been made

Best,

Gustaaf

Hi all,

The Muon L2 slides are posted in Doc DB #1892 and linked to the indico agenda.
