Lateral X-rays with ESS

Lateral X-rays with ESS

• A test version is available in http//www.bo.infn
  .it/opera/scanning/lateralmarks/since the end of
  September.
• Several laboratories started to use it providing
  constructive feedback.
• The current recommended release is 42b (25 Oct
  2007) and it was used for several scan-back and
  totalscan with the Computing Infrastructure
  instead of optical marks.
• The full integration with the Computing
  Infrastructure and DB will require multi-MarkSet
  support (lateral, optical, ).

First tests

• common problems
• - support needed
• - evaluation of the initial markset template
• - transformation from optical markset
• - frequently usage of manual set (bug, mark
  segments outside the vacuum channel)
• - segment finding problems (above the vacuum
  channel
• - continuous monitor of the cloned mark
• - reproducibility when mark is above the vacuum
  channel
• - 2 mark point couldnt be enough
• some advantages
• scan of plate with bad optical marks
• reduction of scan back time
• brick intercalibration matrices close to the
  identity

Work in progress

• A new version will be released in the next days
• map string bug fixed mark side flag are 1 top or
  2 bottom
• Integration with IDMap.dll
• Integration with FlexMap3.dll at the level of
  source code and configuration not working yet
• New configuration parameters to choose how many
  strip samples to be taken and their
  inter-distance.
• Trial to deal with the clone problem
• To be done
• 180-degree plate rotation. Recovery option
• Debug of optical mark
• Mark-to-mark intercalibration
• Optimization of parameters. Study of
  reproducibility.
