	At RCNP, we have been developing magnets utilizing high temperature super conducting (HTS) wires for this decade. They are a cylindrical magnet, two dimensional scanning coils, a super ferric dipole magnet whose coils have a negative curvature. Recently we built a cylindrical magnet for a practical use. It is used to polarize ultra cold neutrons. The maximum field is higher than 3.5 T at the center. We are fabricating a switching magnet which is excited by pulse currents to realize a time sharing of beams in two target positions. In the paper, we report specifications and performances of these magnets.

	Funding: The Mitchell Family Foundation and Texas ASE Fund A superconducting strong focusing cyclotron is being developed for high current applications. Alternating-gradient focusing is provided by an array of ~ 6T/m superconducting beam transport channels which lie in the sectors along the arced beam trajectory of each orbit of the cyclotron. The ~1T sector dipoles, corrector dipoles, and Panofsky type quadrupoles utilize MgB2 superconductor operating in the range 15-20 K. The quadrupole windings make it possible to produce strong focusing of the transverse phase space throughout acceleration. The trim dipole makes it possible to maintain isochronicity and to open the orbit spacing at injection and extraction. The design, development and prototype progress will be presented.
