¥The tests focused first on Integration of SCT into ATLAS run partition
¥New TDAQ version
¥The first day, cooling plant shutdown due to a series
of problems mainly due to the control
system and took 24 h to solve
¥The second day checking
SCT with ATLAS Trigger
¥1kHz random triggers from CTP
¥ some evidence of moving BCID mismatch (not understood)
¥ ECRs ok
¥ Stop at 33K events due to eventfilter not receiving ECRs
¥ECR problem (33K event limit) fixed
by Thilo (ATLAS trigger)
¥Tuesday evening and following night was spent to then
dedicated to adjust the SCT barrel
readout timing for cosmic
triggers
–Used the scintillator trigger from TRT
¥in the pit placed on top of ATLAS (on level 8)
–TRT sector 13 on and partial sector 7
–SCT all 4 barrels (2112 modules) except 3 cooling
loops (~ 150 modules)
¥No EC - barely enough C3F8 for all but focus on integration instead of bringing in endcaps
too (and risking to fall below threshold)
