Timing

Hardware:

• Design of front panel for MIB started.
• Bug in MIB MMC firmware(software) located. Board now powers up in MCH slot.
• AFC: Creotech has confirmed that lead engineer on AFC has left. However, say they intend to quote.
• AFC boards in Bristol will be (re)hacked to match (updated) proposed changes to standard AFC

ProtoDUNE:

• No problems reported with NP04. Timing expert "on site" now Diana Antic until 18th Aug
• Need to ship some fibre splitters for NP02
• Waiting to hear of integration schedule for integrating NP04 CRT and VDE with DTS

Firmware:

• Straw-person firmware built for MIB (that initializes time-stamp based on signal from GIB)
• First iteration of FIB v2 firmware complete

 

Trigger:

• Compiled the list of v4 changes that will need porting to v5:
  1. Changes to TimingTriggerCandidateMaker to allow prescales, fully configurable TC-type outputs per HSI bit input, and configurable readout windows per bit-TCtype pair.
  2. New CTB TriggerCandidateMaker
  3. New CIB TriggerCandidateMaker
  4. Trigger emulation: replay application needs porting/rewriting into v5
  5. Extra trigger ompon (opmon largely missing in v5 anyway)
  6. New online latency measurements in the trigger
  7. Different readout windows for different sub-detectors (e.g. wider readout window for PDS. Might need to rethink the implementation too)
  8. Ability to ignore pileup events/overlapping TCs
  9. Per-plane TA-making & TP inputs
  10. Bugfixing TA/TC adapters/wrappers in the trigger
  11. Filtering out TPs with unphysical time-over-threshold (TP filtering completely missing in v5 anyway)
• Restarted work on trigger opmon in v5
• Started work on porting timing/CTB/CIB trigger changes from v4 to v5
  • Possible MLT changes/workflow restructure needed
• Found and "resolved" the "memory leak" in the trigger -- more testing pending.
• Operations: ADCSimpleWindow trigger algorithm now shown to work with much wider time-window (beyond ground-shake) for highE events.
• Simulation: fantastic work by David D. w.r.t. evaluating needed work for inclusion of trigger algorithms in LArSoft.
  • Clashes with already-existing work effort caused Josh and I to reorganise the format of the DS/PP meetings.

09:15 → 09:30 Activity coordination round table

Release Coordination v4
Release Coordination v5
Iceberg
ND test setups
SW coordination

Speakers: Bonnie King (FNAL), Eric Flumerfelt (Fermilab), John Freeman, Kurt Biery (Fermilab), Wesley Ketchum (Fermi National Accelerator Laboratory)

Software Coordination, John:

• It's been a week since the v5 line has switched over to Spack 0.22.0. As I've heard no complaints, I plan to drop the backup Spack 0.20.0 nightlies today.
• This Thursday at 9:30 Fermilab time / 16:30 CERN time there will be a Software Coordination meeting; the focus will be on C++20, including an introduction of some basic C++20 concepts and proposals for additions (and possible removals) to the Style Guide
