4. LTU – Dry run setup 1 VME processor + 6 TTC partitions + 3 TTCit boards LTU & TTCit boards in VME crate: 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 4 LTU numberLTU nameTTCit number 0x830000LTU_CEDAR0x8a0000 0x831000LTU_CHANTI- 0x832000LTU_MUV0x8a2000 0x833000LTU_LAV0x8a1000 0x834000LTU_CHOD- 0x835000LTU_LKR-

5. Connection tests LTU global mode: TALK -> LTU -> TEL62 ok LTU standalone mode: LTU -> TEL62 ok – connection tested also with TTCit SoB / EoB signals and triggers ok Choke/error – problem with connectors on LTUs – it will be fixed by Marian 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 5

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 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 6

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 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 7

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 board not by its VME address (like 0x832000), but by its DIM name (like LTU_MUV) 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 8

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?) 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 10

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) 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 13

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 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 15

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 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 16

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 30/08/2012 NA62 Collaboration Meeting in Siena - TDAQ LTU status 17
