Ingrid-Maria Gregor, EUDET DAQ Integration Concept How to integrate the DUT hardware with the JRA1 beam telescope? different groups with different detector technologies and different, pre-existing DAQ systems nobody has a large pool of effort to rewrite existing code Use completely different hardware and DAQ for the DUT synchronize only with Trigger, Busy and Reset signals readout software, DAQ and data storage is provided by the DUT user events combined off-line Trigger Logic Unit (TLU) receives trigger and passes it on to telescope and DUT vetoes further triggers (BUSY) records timestamp hardware available file telescope DUT DAQ tel. ctrl intfc DAQ DUT ctrl intfc PC PC file Trigger Logic Unit

Ingrid-Maria Gregor, EUDET Telescope DAQ HardwareHardwareHardware Writer task telescope‘producer’DUT‘producer’other‘producer’ Monitoring task 1 Monitoring task 2 DAQ buffers Monitoring buffers buffers file DAQ Software is divided into many parallel tasks: several Producer tasks read the hardware one FileWriter task bundles events, writes to file and sends subsets for monitoring There can be several Online - Monitoring tasks one Buffer Monitor task allows to see what is going on a FileReader can re-inject data into the monitoring Status Can have several producers (Dummy, Mimosa, DEPFET, TLU) all running together. Data from all of them combined by FileWriter and written to binary file. This can then be converted to a Root file for easier analysis. First version will be available for test beam in June 2007

Ingrid-Maria Gregor, EUDET Transnational Access Imposed by EU to foster trans-European access to research infrastructure Take advantage of it: apply for travel money! For travel to DESY test beam For travel to use any of the infrastructure created within the EUDET initiative Magnet, beam telescope Field cage, SiTPC, Si tracker Calorimeter structure, readout, test stands Open to any European group EUDET or not

Ingrid-Maria Gregor, EUDET Conclusion EUDET is an “Integrated Infrastructure Initiative (I3)” within the EU funded “6 th framework programme” an example of the high recognition of the ILC by the European Union Support improvement of infrastructure for detector R&D with larger prototypes - but not the R&D itself Different Joint Research Activities (JRA) The initiative provides resources which help to proceed towards the next phase of ILC detector R&D Start in 2006: first milestones met, first deliverables delivered EUDET will have a big impact on the Detector R&D for ILC!

Ingrid-Maria Gregor, EUDET EUDET and R&D collaborations  EUDET may be seen as a sort of large virtual “institute” in the overall worldwide ILC detector R&D “collaboration”  Provides resources, takes responsibilities  Make optimal use and avoid duplication on international scale  On sub-detector level, the EUDET activities (JRA’s) are closely coordinated with the R&D collaborations  EUDET is a contract between partner institutes and EC with well defined milestones and deliverables  Needs some own management structure, meetings  Somewhat reduced flexibility  Most challenging impact: need to synchronize the timelines

Ingrid-Maria Gregor, EUDET EUDET Activities Detector R&D Network:  Information exchange and intensified collaboration  Common simulation and analysis framework  Validation of simulation  Deep submicron radiation- tolerant electronics Test Beam Infrastructure  Large bore magnet  Pixel beam telescope Tracking Detectors  Large TPC prototype  Silicon TPC readout  Silicon tracking Calorimeter  ECAL  HCAL  Very Forward Calorimeter  FE Electronics and Data Acquisition System
