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 couldn’t 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. …
