Superconductors for HEP in the next few (10?) years

Europe/Zurich
30/7-018 - Kjell Johnsen Auditorium (CERN)
Description
Of all communities, HEP can fairly lay claim to having been the most consistent, the most committed and the most effective developer of superconductors for magnet applications. Special credit is deserved for our HEP community because the particle accelerators that have provided the principal rationale are only just now transitioning from Nb-Ti to Nb3Sn. Yet HTS materials are certainly seen as part of the FCC toolbox, again demonstrating the long-range vision of our community. My talk addresses the issues of what developments could come from our present toolbox and whether we need to embrace also MgB2 and the Fe-based superconductors (FBS) if we are to be able to build machines like the FCC affordably. We benefit strongly at the MagLab from the desire to push all superconducting magnets into the range above 40 T where only high power (20-30 MW) or short pulse solutions otherwise compete. However, even here high costs of HTS conductors restrict our choices, making a serious attempt to develop more affordable but very high field conductors highly desirable.
