  1. Local Trigger Unit (LTU) status T. Blažek, V. Černý, M. Kovaľ, R.Lietava ComeniusUniversity, Bratislava M. Krivda UniversityofBirmingham NA62 Collaboration Meeting in Siena - TDAQ LTU status

  2. Outline • Dry run setup TALK – LTU/TTCex – TEL62 • Connection tests and Timing issues • Software status • Future Plans NA62 Collaboration Meeting in Siena - TDAQ LTU status

  3. L0 trigger system and distribution Triggers Trigger inputs 40 MHz clock + SoB + EoB signals TALK board BUSY/ ERROR Clock + Triggers + SoB, EoB LTU + TTCex LTU + TTCex LTU + TTCex LTU + TTCex TTC partition . . . . . . . . . . . . . . . . . . . . . . .

  4. LTU – Dryrunsetup • 1 VME processor + 6 TTC partitions + 3 TTCit boards • LTU & TTCit boards in VME crate: NA62 Collaboration Meeting in Siena - TDAQ LTU status

  5. Connection tests • LTU global mode: TALK -> LTU -> TEL62 ok • LTU standalone mode: LTU -> TEL62 ok • connectiontested also with TTCit • SoB / EoB signals and triggers ok • Choke/error • problem with connectors on LTUs • it will be fixed by Marian NA62 Collaboration Meeting in Siena - TDAQ LTU status

  6. Dry run - timing issues • TALK – LTU connection(solved) • LVDS cable termination problem • termination resistor only at the last LTU in daisy chain • TTCex phase instability after power off/on • known problem of TTCex MKII boards • dry run setup: 6x TTCex - 3 are OK, 3 are unstable • need for automatic procedure of phase measurement (in cooperation with TALK) • Counter synchronization after SoB signal • 10 BC clock constant offset between TALK and TEL trigger counters • stable offset → not a problem in normal run of experiment NA62 Collaboration Meeting in Siena - TDAQ LTU status

  7. Software status – LTU LTUdirect software(running on the VME processor) new features: • choke/error support enable/disable • SoB/EoB support for emulations • more friendly counter observing • batch running to configure LTU’s and TTCit’s • color signaling of the Run-control type of state NA62 Collaboration Meeting in Siena - TDAQ LTU status

  8. Software status – LTU LTUDIM software (running anywhere) • functionally identical to LTUdirect • communicating with LTU via DIM • needs common NA62 DIM name server running, currently by Nicolas at PCNA62DCS02.cern.ch • identifies LTU boardnot by its VME address (like 0x832000), but by its DIM name (like LTU_MUV) NA62 Collaboration Meeting in Siena - TDAQ LTU status

  9. NA62 Collaboration Meeting in Siena - TDAQ LTU status

  10. Software status – LTU DIM servers • support for Run Control (tested ok) • support for remote RESTART/SHUTDOWN (tested ok) • currently operated only via Did (universal DIM client) • to be decided whether to be included into Nicolas‘or Valeri’s software • added boot scripts to configure all LTU and TTCit boards in crate and start all DIM servers • currently, we do not have remote access to crate power, however we do need it, can we get help?(e.g. remote customer window in Valeri’s software?) NA62 Collaboration Meeting in Siena - TDAQ LTU status

  11. Did screenshot of running LTU servers NA62 Collaboration Meeting in Siena - TDAQ LTU status

  12. Did – list of LTU services Run Control Reboot Shutdown Run Control NA62 Collaboration Meeting in Siena - TDAQ LTU status

  13. Software status – TTCit TTCitdirect software (running on the VME processor) • GUI concept similar to LTUdirect • added counter inspection • improved snapshot memory (SSM) display • we shall prepare the TTCitDIM version (similar concept to LTUDIM) NA62 Collaboration Meeting in Siena - TDAQ LTU status

  14. TTCit snapshot memory window NA62 Collaboration Meeting in Siena - TDAQ LTU status

  15. Software status – Twiki twiki.cern.ch/twiki/bin/view/NA62/LTUrelatedSoftware • download LTUdirect, LTUDIM, TTCitdirect software • download manuals • installation guides • updated LTU user guide • check for updates NA62 Collaboration Meeting in Siena - TDAQ LTU status

  16. Future plans • Automatic phase measurement procedure • TTCitDIM software • LTU snapshot memory • Improved LTU emulation: • handling of full emulation sequence in firmware (currently implemented in software) SoB– SoBT – triggers – EoB – EOBT • triggering of emu sequence by external signals SoB/EoB NA62 Collaboration Meeting in Siena - TDAQ LTU status

  17. Summary • Local Trigger Unit (LTU) is working well • Most of the issues have been resolved • Software updates -> check our Twiki page • Work to be done before technical run: • auto phase measurement, TTCitDIM, LTU SSM, emulation… • remote access to VME crate power NA62 Collaboration Meeting in Siena - TDAQ LTU status
