Agenda

• DAQ and firmware
• Slow controls
• Software
• Other business

Software task list (draft)

• Near-term priorities (for summer tests)
  • hcana FADC mode 10 code (Mark, David) -- DONE
  • hcana NPS class, replay script and database file (Steve Wood, Carlos Yero, David) -- DONE
  • online display and cosmic calibration scripts (Julie, Pramita, Alexandre, Zheng) -- DONE

• Medium-term (summer - fall)
  • code to handle VTP data in hcana (David)
  • data unblocking (David, Brad, Bryan)
  • geant4 simulation (Marie, Deb)
  • online interface with ET system (Paul, Zheng)

• Longer term
  • offline reconstruction and clustering (Steve Wood, Carlos Yero, Julie and others)
  • offline calibration scripts (??)

DAQ update (from Brad)

• Hakob is continuing with the cable bundling efforts in the ESB.

• Some members of the French group are on-site and working on hooking up temperature and humidity sensors.

• Fernando plans to test the effectiveness of noise suppression at the FADC digitiser, although there are some concerns about this being a long-term solution to the noise issue.

• NPS how-to is on the wiki [1]

Software update (from Zheng)

• Single-arm SHMS SIMC studies were presented.

Software update (from David)

• "Working" decode software (hcana and replay dir) for EEL108 data (cdaql3:/data1/cdaq/NPS/vme2_7.evio.0) is now available:
  • https://github.com/dhamilton-glasgow/hcana/tree/nps_develop
  • https://github.com/dhamilton-glasgow/hallc_replay/tree/nps_develop

• Based on the hcana classes and replay files developed by Steve Wood and Carlos Yero. Still some issues to be tidied up, but it already decodes writes the 26-sample waveform to a root tree.

• Example event display available in replay repo above under macros (also here [2]).

Next meeting

Thursday 13th October at 8.30am EST
