Performance of the First magnet Based on the Common Coil Design
1. The magnet reached plateau performance right away (plateau seems to be on the cable short sample, not wire short sample).
2. Didn’t degrade for a low horizontal pre-load (must for this design).
3. Didn’t degrade for a low vertical pre-load (highly desirable).
4. Didn’t degrade for a bigger hole (real magnets).
The first common coil magnet was built and tested at LBL
A 6 T magnet using low grade (free) Nb3Sn
