    6 SS6 and 8 SS4 rods have been modified (solution 6).

    Of these all of the SS6 and 3 of the SS4 have SR tested and the
    SS6 rods have been through 4 days of MRT running.

     Experiencing time tune errors in the SRT and one rod shows
     no communication.

       [RH: Clean fiber connections thoroughly.]

     High noise seen in deconvolution mode.

     Test results from the MRT for the 6 SS6 rods are basically fine, but

       One module had high noise in deconvolution mode and some missing
       plots.

       Numerous "failure to set MUX" messages

       time tune errors

       header errors
           111000 for one module
           76 for another module

     Main Analyzer used to look at ROOT file and make plots.

       Yuri will analyze the same way.

     Ryan showed several slides

       http://agenda.cern.ch/fullAgenda.php?ida=a054608

       34 rods have been modified based on solution 6 and all 34 have
       been SR tested (Cengiz reported the last test during the meeting).

         5 of the rods have issues:
           3 thermistor
           1 laser
           1 bad noise

       Duccio's request taken into account in selecting rods for
       modification.

       Negative humidity measurements understood - conversion function
       out of date. Readings now appear to be reasonable.

       DCU readings distinguish between one thermistor and two thermistor
       opens. (The 10k thermistors are in parallel). Both cases seen.
       The double open could also be occurring on the Interconnect card.

       18 modified rods have been MRT tested using the extended, 3-day
       scenario

       Scenarios run to completion and data is present so that rods can
       be qualified, but

         Diagnostic log files  unacceptably large. "Megabytes"

         Still see I2C errors 64 and 68 (not seen at UCSB)

         Two modules show 230 errors!  (One of the modules was replaced
         and the error went away.) Need to follow up with Johnson, Matulik.
         Parasitic capacitance?

      No evidence for any new problems on day 3 of the extended scenarios.
      Would like to go back to production (2-day) scenario.

General
_______

    FNAL aiming to ship a crate around 7/20 (~28 modified rods, ~12 rod
    frames requiring modifications/cleaning/inspection). Would like to
    continue modifying and assembling rods at some level to get more
    experience with SRT and MRT systems. Shipment should largely
    satisfy SS6 component of Duccio's request.

Postscript
__________

    The next day Ryan traced one of the double-open thermistor readings
    to a lack of continuity on the Interconnect card. Not clear if the
    problem is a solder connection, via problem, or break in one of the
    layers. Should be able to swap ICC's..Looking into single thermistor
    open example.
