Oral presentation (20 min) + Q&A (10 min)
The high field magnet program is an R&D activity focused on the construction of 14 T dipole prototypes in Nb3Sn, proving the HTS technology for main accelerator dipoles in the 14-20 T range, and developing the superconducting technology for particle physics.
In this talk we will outline few R&D guidelines that concern test and diagnostics. The recent studies and proposal for an FCC-hh operated at 4.5 K, as in the baseline for the SppC, would require the ability to measure the temperature margin in magnets tested at 4.5 K. Another critical aspect is the measurements of hysteresis losses during ramp, that are one of the main bottlenecks for the energy consumption and dimensioning of cryogenic system. Finally, the measurement of the stability of transfer function and low order multipoles during magnet ramping for both HTS and LTS is a fundamental proof of the viability of both technologies for main magnets in accelerators.
