LTU – Dry run setup • 1 VME processor + 6 TTC partitions + 3 TTCit boards• LTU & TTCit boards in VME crate:

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

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

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

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)

Software status – LTUDIM 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?)

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)

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

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

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
