Superconducting detector solenoid magnets for particle physics have advanced with Al stabilized superconductor and indirect-cooling technology, in particular, for large-scale particle detector systems in colliding accelerators, since 1970s. This paper will introduce the key technologies to realize “thin and transparent” solenoidal magnetic field for momentum analysis of particles passing through the superconducting coil with minimum interaction, and briefly discuss the future prospect.
