Subject: summary of issues from EM timing IRR
Date: Friday, July 09, 2004 2:50 PM

Dear EM Timing interested parties,
     Thanks to Max, Dave, Dervin and Rob for their
comprehensive summaries demonstrating the tremendous
progress made on the EM timing system.

Remaining issues not (or insufficiently) addressed in the talks:
 1) Must re-check ASD's for mechanical fit; especially check
    front panel hole.  Peter Wilson will help.
 2) Should request two quotes for the long cables: one for
    an order of 4 cables, and one for an order of 8.
    4 is probably enough spares, but we might want
    to get 8 if the price difference is marginal.
 3) Require confirmation from Marco Cordelli
    that Frascati will send to Fermilab pre-assembled
    bulkhead boards.
 4) Require the cost estimate of additional equipment.
    This should be a detailed list that has
    cost estimates for each item.  For example:
    item: 8 ASD Boards, provide Parts Cost,
    PCB Cost, and Assembly Cost.
 5) Does the 27 TB/ASD pairs currently tested and available
    for CEM include the four which are already installed?

Installation strategy:
Compile a procedure checklist for the installation
of one unit of EM timing (a wedge?) which can be used to verify
at any given time the status of the installation/checking and
can be used to supply serial numbers to the database.
Begin installation as soon as we get new, healthy, tested TB's.
Install most difficult wedges first (top and bottom).  Move toward
the middle (3 o'clock and 9 o'clock).  Stop installation when
we don't have the full complement of parts to assemble a whole
wedge.  Do not do any tricks to maximize coverage which will have
to be disassembled later, and require changes to the mapping which
make data analysis difficult.

We request a weekly status report on parts procurement,
and wish to re-convene at the end of September (propose 29.Sep.
but precise date/time to be determined) for assessment of
the ongoing installation.

Best wishes,
Camille, Steve, Mike, Pat, Rob, Willis, and Peter
