TL;DR: In this article, a model assuming the existence of periodic disturbances is proposed in which the disturbance frequency is directly proportional to the ramp rate of the square of field, and a semi-empirical formula was developed which fits the ramp-rate limitation data of both the US-DPC large coil and the 27-strand cable.

TL;DR: The United States Demonstration Poloidal Coil (US-DPC) as discussed by the authors was designed for 10-T operation with charging and discharging from zero to full field at ramp rates of up to 10 T/s.

TL;DR: Incoloy 908 is a nickel-iron base superalloy with its coefficient of thermal expansion and mechanical properties optimized for use in Nb3Sn superconducting magnets.

TL;DR: In this paper, an experimental study of the influence of design parameters on the short sample critical current of Nb 3 Sn cable-in-conduit conductors at 42 K is presented.

TL;DR: In particular, the dependence of critical current on longitudinal strain becomes dramatic with increasing magnetic field, and therefore, any optimization of high field critical current in Nb3Sn composites must consider the longitudinal strain state as well as the microstructure of the superconductor as discussed by the authors.
