MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 2 Achievements since CM24  DAQ and Controls Review  Factor of 5 increase in # of particle triggers per spill  FADC Firmware upgraded Factor of 4 reduction in data size  Trigger Debugged  Problem with Event building under control  Target DAQ des-integrated

DAQ Review  Details presented at VC 121  The DAQ Review is Done !  The DAQ Review is Done !  Very useful comments have been received  Detector DAQ appears to be in shape and should allow data taking for Step III and beyond  Unified Controls, Data Flow and Online Database are more recent projects and the committee has noticed it’s not yet mature Need better integration DAQ/Controls More thinking on Online Data Buffer Disk Access  Serious concern about the man power available for Controls MICE VC June 2009Jean-Sébastien GraulichSlide 3

Reminder  The DAQ Spill Gate has to be checked before data taking Documentation available Adjust Width And log !!! MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 4 TOF1 Accepted Particle Trigger GVA1 = Part. Trg Request Spill Gate

Trigger debugging  Trigger signal generation was in “update” mode Went unnoticed at low rate Introduced variable dead time difficult to control Caused saturation  Solved MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 5 Particle Trigger request Accepted Particle Trigger

Event Building  Synchronization can be lost because of Unstable electronics in DAQ trigger distribution Unstable behavior of the VME/Pci Interface  The DAQ software release the busy and enables the DAQ trigger receiver channel after readout Must go through the VME/Pci Interface It happens that one of the two commands is not executed properly… Unpredictable Cured only by a power cycle  Has to be monitored MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 6

DAQ Trigger Monitor MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 7 Number of LDC receiving a DAQ Trigger per DAQ event LDC Number counts # of DAQ Triggers

MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 9 Front End Electronics  TOF2 1 TDC and 5 FADC to be installed Will require upgrade of the rack layout in Control Room  EMR: Electron Muon Ranger (aka SW) Prototype of Front End Board exists BUT : We consider going for another ASIC (Amplifier-Shaper- Discriminator) Buffer Card will be developed in Geneva More details in Daniela Lietti’s talk

MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 10 CAM/DAQ Interface   Double link EPICS should know the DATE status A summary of EPICS data should be inserted in the online data stream   Date Status Monitoring James Leaver has provided EPICS Server EPICS Client Test Software Status Display Next step: A small piece of code reading real status from DATE

MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 11 CAM/DAQ Special Case:   Target DAQ   Target data is really both CAM and DAQ Double flow is implemented Based on a single I/O software -> No issue with format change   Waiting for the target to be online for final tests But in the meanwhile the code vanished…   Will require dedicated testing runs

MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 12 Schedule Milestones  From CM23  TOF2 Shaper/Splitter Productionmid March need testing  DAQ review June 09  Upgrade of fADC firmwareJuly 09  CAM data in Online Data StreamJune 09 -> Nov 09  Tracker integrated in DAQ and OLMJuly 09 -> Jan 10  TOF TDC Clock SynchronizationJuly 09 -> March 10 More complicated than first thought. Need a dedicated board  Burst Gate Signal in the Trigger SystemNeed aupport here  Approval of SW/EMR Front End ElectronicsIn Proto phase  Production of SW/EMR Front End ElectronicsSept > Jan  TOF2 DAQ InstallationDec 09

Summary  DAQ review passed  Data rate increased by a factor of Mainly due to FADC upgrade  Trigger system upgraded to handle this rate  Event building problem understood and under monitoring  Next steps Interface with CAM Integration of TOF2 MICE CM25 Nov 2009Jean-Sebastien GraulichSlide 13
