摘　　要：Nowadays,inertial confinement fusion(ICF)research related to noncontact positioning and transport of free-standing cryogenic targets is playing an increasingly important role in this field.The operational principle behind these technologies is the magnetic acceleration of the levitating target carrier(or sabot)made from Type-Ⅱ,high-temperature superconductors(HTSCs).The physics of interaction among levitation,guidance and propulsion systems is based on a quantum levitation of high-pinning HTSCs in the mutually normal magnetic fields.This paper discusses current target delivery strategies and future perspectives to create different permanent magnet guideway(PMG)systems for ICF target transport with levitation.In particular,several PMG building options for optimizing both suspension and levitation of ICF targets using an HTSC-sabot will be analyzed.Credible solutions have been demonstrated for both linear and round PMGs,including the ones with a cyclotron acceleration process to realize high-running velocities of the HTSCsabot for a limited magnetic track.Focusing on physics,we describe in detail the main aspects of the PMG building and the results obtained from computations and proof of principle experiments.High-pinning HTSC magnetic levitation promises a stable and self-controlled levitation to accelerate the ICF targets placed in the HTSC-sabots up to the required injection velocities of 200 m/s and beyond.
