  1. May 2003 Beam test Data Acquisition report L.Mirabito CERN & IPNL

  2. People • Slow control & Safety • E. Carrone, A. Tsirou, P.G Verdini, O. Militaru • Fast Control & database • F.Drouhin, L. Gross, D. Vintache • Trigger and Beam control • W. Adam, W. Beaumont, P.G Verdini • Run Control • R. Chierici, F. Drouhin, M. Gulmini • Data acquisition & Monitoring • L.Mirabito • Data Handling Offline, FU+ORCA integration • T.Boccali, G. Bruno,V. Ciulli, M. D’Alfonso , N. DeFillipis, I.Tommalin, I.Reid L.Mirabito CERN & IPNL

  3. Trigger system • 2 scintillators with PM in coincidence • 2 Trigger systems • TSC with external clock & trigger for standalone DAQ • Antwerp Trigger card + TTC system • Trigger Pattern selector • FED & APV clock line fan out • FED trigger throttle adapter card from Pisa L.Mirabito CERN & IPNL

  6. Debug week • Three systems in parallel running each • One PC with • 1 TSC • 2 or 3 FED • One PC with • 1 FEC + OFEC • 1 FireWire disk • From DAQ point of view • Quick integration • 2 h to start physics run once HW is OK • FED sampling tuning with ticks • Opto gain adjustement with ticks • Latency scan to identify trigger position • Pll scan to refine sampling • Smooth running • Few crashes • User friendly Run Control TSCSupervisor, TrackerFedPmc, dataSender TrackerTriggerSupervisor 1 RU, BU, EVM, FU, rootWritter L.Mirabito CERN & IPNL

  9. Ieee1394 disk Fec system (TEC) Fec system (TOB) L.Mirabito CERN & IPNL

  10. TIB TOB integration • Structure • Keep structure of FED PC’s with one dataSender per PC • Keep FEC PC’s as well • One PC for RU’s, BU, EVM and FU • One PC for data writting and monitoring • Commissionning • FED Sampling adjustement done on FED basis (internal 2.5 ns delay) • Keep same latency and mode to cross check APV addresses • Trigger latency scan to find rough delay between 2 systems (~ 75 ns) adjusted with PLL coarse setting • Pll fine scan to achieve alignement wrt to particles L.Mirabito CERN & IPNL

  11. Integration • Two setup running coherently after few hours • Configuration mistake (Peak TIB, deconvolution TOB) • Alignement runs • 100 spills per run needed • Demonstrate commissionning capability of the system • Two independent rings with 15 m of fibers length shift can be easily aligned. • Tools needed to automatise analysis and settings • TEC integration • Failed due to TEC ring instabilities with TTC system (to be retried) L.Mirabito CERN & IPNL

  12. Ergonomy • Run Control with standard RCMS • Easy configuration • Run parameters accessed by daqlets • DCU readout and storage • IMS introduce with storage of error messages (lack of user widget) • Very good support from M.Gulmini • Keep old JAS based monitoring L.Mirabito CERN & IPNL

  14. Failures • Slink dataSender • New PC bought to handle GIII receiver needs additional patches to deal with • Debug starts on Monday • FED hanging • One extension PCI box exhibits last 4 days several failures on FED configuration requiring PC reboot • Trigger card • One Antwerp trigger card failed after 6 days and has to be replaced. L.Mirabito CERN & IPNL

  15. Performances • Up to 2500 events / spill • Limitations due to ROOT compression algorythm performances • 20 Mb/spill ~ 1 Mb/s • Stable running except • Noise reset on TOB AOH • Ring problem on TEC DOH-ICB • FED hanging on configuration (TIB box) L.Mirabito CERN & IPNL

  16. In progress • xdaqCluster • Automatize start of executives • Slink integration • FED VME plugin next year • FU+ORCA • Debugging last week • To be tested in coming days • CARROT integration ? L.Mirabito CERN & IPNL

  17. Conclusion • First beam test which profit from XDAQ architecture • Scalability • Adaptable • Despite its complexity, new tools like RCMS eases usage for newcommers. • Gigabit network and IEEE1394 disks improved performances now limited by CPU performances on data storage side ( factor 2 easily achievable) L.Mirabito CERN & IPNL
