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

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

Hi Andy, (cc. John H.)

        Good points; I was maybe working too hard to keep
the replies short, but figure there will anyway be an
accompanying verbal discussion where I can expand.
        Concerning the 25 Gbps, my understanding is the
testing by BNL is very promising on that front.  It would
be good to hear from you/John H. if that is true.  I did
not write it down, since those tests were done under DOE,
which might launch another discussion ...  However, it
would be good to know the level of confidence there is
already now.

                John
