      Grade of importance of the external issues to the coil

      In the paper I will include the stress reduction, according to the model, with the mitigation measures.

      Collaring is not modelled. It directly applies to the coil the desired pre-stress displacement

      Do previous model DP101 have the same range of values after cooldown in the bullets?

      New slide 32: bullets in magnet DP101, similar spread to the aperture SP301 (DP301) after cooldown

      New slide 33: boxplot of delta cooldown in all the 11T model magnets. Aperture SP301 (DP301) has the smallest range of bullet values after cooldown among the double-aperture magnets

      Do the bullets have the same compression after and before a quench?

      New slide 34: The compression in the bullets is fully recovered after quenching, see the graph in slide 34.

      More detailed the explanation of the functioning of the end cage

      Coil 108 seems to have significant damage in the mid plane and head coil head inner layer segment. The damage was not generated during the assembly of the presented magnet because coil 214 has no similar limitations.

      Corrected

      The end cage rods remain under tension, ensuring coil head compaction. However, performance limitations of the coils prevent definitive conclusions regarding potential enhancements in magnet performance  axial support improvement.
