Why Start HTS Magnet R&D Now?
We are almost there!
Both in terms of Jc (~a factor of two) and in wire length (a factor of 5-10)
Performance has become enough to do credible magnet R&D
Cable can carry 5-10 kA and hybrid magnets can create 15+T
It takes long time to do magnet R&D even with known NbTi technology
- Allow, at least five years for this new and challenging R&D
- Address magnet technology issues (allow new ideas to be tested)
- Address issues related to field quality, etc.
In the meantime HTS performance should improve by a factor of 2
With both done in parallel, we can make an informed decision in ~5 years
- To do that, the right time to start HTS magnet R&D is NOW!
