Minutes of the Trigger Operation Meeting (, 2007)

Operations

• A couple of incidents of both minor (just start new run) and major (power cycle TSF crates) trigger damage. Mike P. suggested we swap the ROM boards, as they've seen this problem before as a symptom of single board processor issues. Matt Weaver will do this when he has the chance. This may not fix the problem but it would at least rule out ROM problems.

EMT

• Occasional cable errors show up in QA monitoring plots. Mark will investigate what type of error it is and whether it is causing problems for data-taking.
• Board is back from Lupe and has been fixed. It's in IR2 and will be tested when the opportunity arises.
• Efficiency study: will be summarised in collab meeting talk and BaBar note.
  Further studies - scatter plot of ADC counts vs EMC cluster energy for data and MC to check conversion factor.
• Should check when/if last EMC source calibration constants were uploaded.
• Should check if EMT is calibrated when EMC standalone calibration is performed.

Data Quality and Monitoring

• No problems in data so far.
• Still no ideas about what causes removal of connecting lines on strip charts. Also still need to adjust scale.

Trigger Configuration

• Hojeong: see summary page for details of progress on statistics study and also filter study.
• Rainer: see folder for details of status of trigger emulation study. .tcf and *diff* files summerise the different stages of tightened trigger configurations, for those of us who've forgotten over the previous months. .ps files show effect of the different configurations.
