    Entry number 52972

    keyword=DMCH #8

    Check the DMCH #8 after transportation and found first Top black 3M connector (0A->7A) slightly damaged.
    Broke the plastic on left --> BE VERY CAREFUL NOW WHEN PLUGGING BECAUSE THERE IS NO MORE SAFETY FOR SENS OF PLUGGING IN!

    Put back the pins on left straight because they have been twisted (lightly)


    Front -Back Coincidence with GENEX (DeltaT=23nsec) gives

    RMT1/RMT3/RMT5/RMT7/RMT9/RMT11/RMT13/RMT15
    61 / 63 / 71 / 68 / 63 / 63 / 71 / 67
    so for physics ( DeltaT=17nsec) must be reduced by 34 DAC units
    27 / 29 / 37 / 34 / 29 / 29 / 37 / 33
    TO BE CHECKED WITH PHYSICS

    Linearity checks

    LIN1=50 LIN2=55

    Try DMCH mode but nb events=100 too small
    Runend failed....

    Rebooted CODA with Ts_full


    Caval & Camont for DMCH8=10

    Run 14713 miss one channel
    Run 14714 has all channels ( 8 MTs for Fronts)

    Verif. of RMK's from Orsay
    RMK0=240
    RMK2= 255
    RMK4=180
    RMK6=255
    RMK8=235
    RMK10=255
    RMK12=235
    RMK14=255

    did not work well.
    Found swapped cables several times>

    references runs are now 14731, 14732 and 14733 for RMK check
    but seems that the delay between signals is just too short.
    However the RMK values look stable compared to measurement made at Orsay in November.

    The previous measurements have to be redone because of inverted cables

    NOW HF1 and RMK check : Direct :gene IB (Sync.)
    Buddy : GADGET Internal (Async.)
    runs 14734 and 14735 : give the limits of buddyfication for RMK and HF1=7
    adjustments

    BACK to Cavals and Camonts with good cabling
    run14736 to look on buddy spectra (mode FifB-Bud)
    run14737 to look at MT spectra directly (mode FifB)

    @2.30 p.m.
    NOW back to vxWorks for LIN and RMT because of bad cabling at start.
    file
    LIN1 = 45 and LIN2 = 57 new values
    [lin-1320rpm-slot2-4-d lin-1320rpm-slot2-4-dec-2002-GADGET-2.txt ]


    Check also RMT were good!

    USE GADGET to locate Caval run 14739
    USE GADGET to measure Deadtime of MT (FifB)

    3.30 p.m. Time for Weekly conference
