13. CHAMBERS INSPECTION AND FIDUCIALIZATION FOR CBXFEL (TUO06)

Davide Bianculli (Argonne National Lab)

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...

14. [Title inquiry in progress] (TUO07)

Reliable tunnel magnet alignment demands a systematic precheck strategy to decide whether a candidate single-station setup is sufficient, requires additional key points, or should be adjusted before full observation. This work introduces a station precheck and decision-support prototype that integrates uncertainty-aware metrology with structured scene reasoning.
The uncertainty model combines...

15. High Precision Alignment R&D Activities in NSLS-II (TUO08)

Chenghao Yu (BNL)

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...
