  1. From recent Offline Commissioning work • Offline Commissioning andMonitoringmeetings (March) • Cosmics Triggering • Triggering possibilities with Tiles, Muons (RPC) • Dedicated Tiles triggering system built • Discuss how to run this trigger to other systems • Discuss how to establish a timing signal (à la testbeam TDC) • Discuss how this timing gets into offline reconstruction • Discuss how timing is incorporated in MC, in Calo digitization • Next general commissioning (18.4.) dedicated to this • Monitoring • Much progress in TDAQ dataflow <=> Athena by Barcelona group • Next offline commissioning meeting (26.4.) will go into detail of this Cosmics / Monitoring

  2. Cosmics in Cavern (in 10 ms), G3 ~ 5 million cosmic muons enter the cavern in 15 minutes also ID (SCT+TRT barrel surface cosmics running this fall Rob Cosmics / Monitoring

  3. Tiles: 9U coincidence boards 9U VME board designed and constructed at Chicago for triggering on cosmic-ray muons in TileCal. - FPGA programmable - 12 SD / board Two boards allow initial trigger on 6 top and 6 bottom modules for | η | < 0.8 and Δφ = ±0.3 4 to be built in total by June ‘05 R.Teuscher Cosmics / Monitoring

  4. PT/EF design and TDAQ dataflow Athena HLT Interface EventLoopMgr execute event EFSubDetectorFragment FullEventFragment PT (Processing Task) can be seen as TDAQ application that receives events form a source and passes them to Athena for processing • efhlt – abstract interface between DF and HLT for event processing • PTIO (PTClient) – event data exchange between PT and EFD via UNIX socket: The algorithms running in Athena can produce data in the form of objects in Athena Transient Event Store Currently: PESA produces the EFResult object, serialized data taken from EFResult object and wrapped in form of EFSubdetectorFragment S.Sushkov DF DF PTIO EFD PT implements Event Loop Cosmics / Monitoring

  5. Example implementation for monitoring DF EMS TES Object EFSubDetectorFragment FullEventFragment Gatherer Athena histogramming service DF EFD EFDptio Athena DF PTIO Interface HLT Interface Athena persistency service PT implements Event Loop EventLoopMgr execute event EMSptio Database Currently we are able to receive as input to PT only FullEventFragments • propose currently to build event up to FullEventFragment before PT (RCD/EMS) • later we may consider/implement possibilities to receive other SubFragments and recognize them In order to keep PT code universal for triggering/monitoring/calibr/something_else, we are going to generalize software structure: make PTIO interface abstract, and particular implementation of PTIO interface will be configurable/loadable library (next slide) S.Sushkov Cosmics / Monitoring
