      Description

      In the run 21, some of the fiducial fibers gradually moved during the convergence, as reported (Notes_Run21_20250406.pdf). Out of 235 convergence, 90 (for 55 different designs) showed such possibility. It caused bad flux loss sometime.  When PFI was tested in Taiwan, interference between FF and cobra were reported and at that time some cobra limited its theta range.

      We need to check/discuss

      • If the latest xml file has correct theta range
      • How to avoid interference in the future
