Rapid-cycling ReBCO dipole magnet concept for muon acceleration

We present a concept of the superconducting ReBCO dipole magnet for ramping range up to 10 kT/s as possibly required for the muon acceleration (Chance 2023) in a future Muon Collider presently under study (Palmer 2013), (Accettura et al., 2024), (Jindariani et al., 2025). This approach is based on the 6 kA CORC-like cable constructed with 12 ReBCO tapes of 2 mm width. Based on theoretical prediction (Solovyev et al., 2023) there is a linear scaling of the ReBCO cable hysteresis loss with the crossing magnetic field possibly generating power loss independent of the magnetic field ramping rate. This feature makes this ReBCO cable suitable for the construction of rapid-cycling magnets. In this work we outline the design of a dipole magnet for 2T gap magnetic field and discuss the helium coolant parameters for the minimal electric power.
