sPHENIX EMCal discussion

[EdwardOBrien <eobrien AT bnl.gov>]

    Dear all,
     John Haggerty copied me on the proposed outline of the EMCal
    section of the sPHENIX pCDR. It looked quite comprehensive but
    I'd like to request two additional topics be added to the subsection
    on the Overview of the Detector.
    1) Justification or Rationalization of the design choices for the subsystem.
    Why did we choice this energy resolution, granularity, material, geometry, photosensor.

    It may be obvious to us since we've been working on it for a long time but it won't
    necessarily be as clear to those at DOE or other nuclear or high energy physicists,
    especially reviewers, that don't work at RHIC.

    2)Include a text-based or tabular description of the steps that takes us from
    where we are now to a completed detector ready to install. A tabular version of this would
     be ideal, but I am uncertain how easy this would be to come up with. A
    text version would be of the form:
   
    Production and bench testing of both 1-D and 2-D projective towers between now
    and the spring of 2016. Beam tests at FNAL with  an array of 1-D projective modules
    in April 2016 with prototype sPHENIX Calormeter electronics.
    Beam tests with an array of 2-D projective modules at FNAL in the Fall of 2016
    followed by the start of the design of full-scale supermodule prototype.
    Conceptual design of the EMCal throughout FY2017. Bench tests of the
    full-scale prototype starting in mid-2017 using  the next round of the calorimeter
    electronics. Final engineering design of the EMCal starting in early FY18 and
    concluding in 4QY18. Start procurement process for major EMCal production
    components 4QFY18. Production of towers beginning in spring 2019 ….. 

    I've attached the amended outline of the EMCal section.
