U.S. ATLAS HL-LHC Upgrade LAr Level 2 and Level 3 Managers Mailing List

[John Parsons <parsons AT nevis.columbia.edu>]

Hi Andy,

	The additional bullets look good.  I would still suggest to be more 
prepared to discuss issues like how long the QC tests take for each 
production SRTM board (and whether you have sufficient manpower and time 
in the RLS), what sort of tests are required (ie. what is measured, what 
is stored in the dB etc.), and what tests need to be done upon arrival 
of the SRTM boards at CERN to "accept" them (and move subsequent work to 
the operations program instead of the construction project).  From 
discussions with the committee so far, we might well get such questions, 
and your slides do not really address these issues. I still think a 
couple of dedicated slides would be useful to proactively address these 
issues, in case we are indeed asked.
        Regards,
                John
