All Candidates 2010 - 20132013
DATA LADDER DDL REASON SOLUTION
08/02/2013 A618 513 Ladder become noisy (Pedestal didn't work) FEROM Firmware reloaded
07/02/2013 523 High Data Size (Pedestal didn't work) FEROM Firmware reloaded
30/01/2013 519 High Data Size (Pedestal didn't work) FEROM Firmware reloaded
29/01/2013 516 CDH error (miniEventIdMismatch) FEROM Firmware reloaded
2012
DATA LADDER DDL REASON
19/11/2012 513 CDH error (miniEventIdMismatch) FEROM Firmware reloaded
31/10/2012 A520 514 Ladder become noisy (Pedestal didn't work) FEROM Firmware reloaded
31/07/2012 513 CDH error (miniEventIdMismatch) FEROM Firmware reloaded
2011
DATA LADDER DDL REASON
07/09/2011 514 CDH error (miniEventIdMismatch?) FEROM Firmware reloaded
03/08/2011 514DDL busy, but no more infos from the logbook. Maybe solved with FEROM
power cycle FEROM power cycle?
2010
DATA LADDER DDL REASON
12/07/2010 521 DDL busy after moving from Supersafe to REAdy FEROM power cycle
Measured and Integrated Dose
• RAMSES Sensors, but dose given in Sv and not in Rad
• No sensors exatly near our racks (see next slide map). The two nearest (on A side) are one on the miniframe (PMIL2513) and one at the edge of the ALICE Cavern (PMIL2511). Our racks are in between. Not sure if there are sensors on I side
• Two values of measured and integrated dose, one per sensor

Conclusions
• Some cases clearly associated to a peak in the radiation measured appeared just before the event:– DDL 513 event 1, DDL 514 events 2 and 3
• Almost all the others happened during STABLE BEAMS but no evident peak in the measured dose wrt immediately before or after.
• Which action has to be taken?
