filewriter: periods #93

Description

@Tom-Willemsen

Entries under the raw_data_1/periods group.

Some of these entries are just per-period versions of dynamic metadata that exists elsewhere. These items should be straightforward.

Other items involve details of hardware-period schemes, which need discussion with DSG to work out how the new electronics treat these.

Questions

HRPD-X will likely not use periods, but we need to do research to understand:

  • How exactly does the streaming system handle hardware periods, DWELL periods, and suchlike (talk to DSG)
  • Which elements of the current format make sense in streaming system?
  • Which parts of the raw_data_1/periods group does mantid minimally require to load a file? (talk to Mantid team)
  • Which parts of the raw_data_1/periods can mantid read for instruments that run in multi-period mode regularly? (talk to Mantid team)

Potential differences from existing files

  • Per-period metadata: no differences expected
  • Hardware-period related datasets: to be determined, pending discussions with relevant teams about how hardware periods work in new system.
