Multiple chambers for the cavity-based X-ray free-electron laser (CBXFEL) have been designed, assembled, measured and tested by Argonne National Laboratory (ANL). The fiducialization and the features inspection of all the critical components are performed by mean of both probe-contact articulated arm and non-contact video microscope. All metrological aspects for crystal diamonds and...

Reliable magnet alignment requires assessing measurement capability before field implementation and selecting effective corrective actions when a measurement plan is insufficient. This study presents a task-specific, intervention-aware virtual metrology framework for the HALF GD04 magnet alignment. Laser tracker observation uncertainty is propagated through target coordinates, rigid-body pose...

NSLS-II is planning an upgrade to NSLS-II U, according to beam dynamics, the current lattice design requires that the adjacent PMQ magnets on a common girder to be aligned within 15-micron (RMS). It is a much more stringent requirement considering all the error factors involved. The approaches for magnet fiducialization and girder assembly will be investigated and tested. Recent experimental...
