Run Modes (per DocDB 9677)

No. Mode Comment
1 Continuous main DAQ mode Similar to final 'triggerless' far detector running mode, i.e. parallel trigger farm looks for nice muons in real time.

Needs ZS of TPC data to work.

2 Triggered main DAQ mode Main selection is external trigger counter
3 Immediate triggered mode Use TOC triggered mode (only outputs data in window) or SSP triggered mode to avoid bottleneck (this is a fallback option of there is bottleneck in either RCE or SSP data)
4 Triggered window mode TPC in triggered non-zero suppressed mode (use before we are happy with ZS in RCE)


Issues that need to be clarified

  • Purposes and architecture of the proposed online farm
  • Design of the metadata
  • Handling TPC stream data within the framework which is trigger-oriented, issues of timing and multiple interaction in temporally close slices
  • Possible necessity to duplicate parts of raw data to create overlaps, in order to make practical operation of the online farm
