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

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

Hi Andy,

        Thanks for the fast reply.
	We should definitely put Kj's BCP on Mike's list.  The PO knows all 
about it, and has already agreed that it should be supported.  I can ask 
them when they would like us to bring it forward.
	Concerning the SRTM, it is a bit more complicated.  CERN is holding 
(for now) a hard line against any further LS3/Run 4 delays.  Reality 
might (will) likely take over at some point.  However, I see no chance 
that will happen during the remainder of Fabiola's term, and even more 
certainly not before our review in July.  That means the July review 
will have to deal with the current CERN schedule, including the issues I 
raised below.
        Regards,
                John
