The DAQ Review is Done ! The DAQ Review is Done ! Very useful comments have been receivedVery useful comments have been received Detector DAQ appears to be in shape and Detector DAQ appears to be in shape and
should allow data taking for Step III and should allow data taking for Step III and beyondbeyond
Unified Controls, Data Flow and Online Unified Controls, Data Flow and Online Database are more recent projects and the Database are more recent projects and the committee has noticed it’s not yet maturecommittee 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 Serious concern about the man power available for Controlsavailable for Controls

Synchronization can be lost because ofSynchronization can be lost because of Unstable electronics in DAQ trigger distribution Unstable behavior of the VME/Pci Interface
The DAQ software release the busy The DAQ software release the busy and enables the DAQ trigger receiver and enables the DAQ trigger receiver channel after readoutchannel 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 monitoredHas to be monitored

Front End ElectronicsFront End Electronics
TOF2TOF2 1 TDC and 5 FADC to be
installed Will require upgrade of the
rack layout in Control Room
EMR: Electron Muon EMR: Electron Muon Ranger (aka SW)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

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 2009 Jean-Sebastien Graulich Slide 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
