Data shift report (12-JUN-2000 to 16-Jun-2000)

 GENERAL COMMENTS:

During this week the acquisistion got severeal problems as follows:

12jun2000 8:35
         run19628 found stopped
                    uVAX1 chrashed @~ 12jun2000 02:00
                    the BARI TRIGGER crate was off because of a fan failure
                    uvax1 received last trigger @~ 2 o'clock}
                    replaced fan unit (SM1 RACK 16) by Roberto Giuliani
         run19631
                  - stopped to put back in acq 6B14-1
                  - noisy PHRASE fan unit changed and fixed (sm2 rack9 cr4) - by Roberto Giuliani

14jun2000
         run19634 stopped by Patera because the SM2 streamer HV
                  had to be turned off to allow the CR39 extraction.
         run19635 PHRASE only - badly started - (the uVAX1 synchronization
                  wasn't excluded)
         run19636 PHRASE only - (again for the same reason)
         run19637 started w/o uvax1 - (at last the uVAx1 sync. was excluded !!)
         run19637 stopped to put uvax1 in acq
         run19638 crashed --> target buffer busy

15jun2000
         run19642 @~ 17:20 BLACK OUT !!!
         run19643 full macro@20:17
         run19643 stopped @20:22 (no phrase triggers from SM3/4)
         run19644 @19:22 started full macro
         PHRASE power supply replaced (SM6 RACK9 CRATE 3) - by Roberto Giuliani

16jun2000
         run 19645 stopped by Roberto Giuliani to take out uvax1 from the acq.
         run 19646 started w/o uvax1 in order to fix the usual ERP counters
         which didn't load LUTs (1C13,1C14,1C15,1C16)
         run 19646 stopped (badly started because the uvax1 sync. wasn't turned off)
         run 19647 started w/o uvax1 (succesfully !!)

Furthermore, I found that all MACROUSA restart jobs were missing while DO_MONITOR
crashed on thursday and I re-launched:

 RS_DISKMON_VXB
 RS_PREP.COM
 RS_DISKMON_OUT
 RS_WWW
 RS_LGB
 RS_MON
-----------------------------------------------------------------------------------------
  PMT CHECK:

  This week the whole SM5 was checked and here's the list of bad PMT signals:

  - Undergain:
      0 5E01-0 found @ -3.6mV (bright and filled)
      0 5T01-0 found @ -3.7mV (Bright & filled)
      0 5T07-1 found @ -3.7mV

  - Overgain:
      o 5B12-1 found @ -4.5mV
      o 5C15-1 found @ -4.3mV

  - Others
      o 5W04-0 bright

   TRIGGER RATES:

           ERP --> 3B07 ~5.5mHz
           ERP-GC --> 1E01 ~70mHz, 6W12 ~100mHz, 6S04 ~110mHz, 6S07 ~70mHz.
            TOHM --> 2T01 ~9mHz,4T13 ~9mHz
           LIP --> 1B16 ~0.3mHz(!), 1B12~0.9mHz, 1B14~1.1mHz, 2E10 ~10mHz,
                      3E04 ~6.5mHz, 6T12 ~12mHz
           PHRASE --> 1E09 ~30mHz, 2W13 ~25mHz, 5W11 ~40mHz, 5T06 ~25mHz
 
   FMT rates: we got no more than one FMT trigger per uvax and they seem to
             be justified (by checking the Lane's EVD).

   LAMOSSKA:

      There are still many "not justified" LAMOSSKA triggers from SM5 (LAM5-0).
    
   CSPAM efficiency:

      The only box with systematic inefficiency is 3B07 (~40%).

   LIP efficiency:

      Low efficiency for 1B12, 1B14, 1B16,1T15, 1C08, 1C14, 1C15, 5T02, 6C09
      and 6C10.

   SPU: still hits on ERPI, ERPII, SPARE and LED on uVax1 (sometime 1/2 VETO
         bits too).

   STOP MASTER:

     Some fake hits on SM4%1@CITm. (No more than 4 hits per run)

   NO-Q-RESPONSES:

 There are still a couple of no Q responses but no more than 7 per run
 from M:2,B:2,C:5,N:21 and one from M:3,B:2,C:5,N:21 every ~10 runs.
 During these events, ERP triggers on SM3 but sometimes it wasn't
 caused by real events, pratically the west attico counters are not
 always involved as we believed.
