	Progress is reported in developing textured-powder Bi-2212 cores as a new approach to Bi-2212/Ag wire tech-nology. The process builds upon earlier work in which Bi-2212 fine powder can be highly textured in its a-b plane orientation and fabricated into square-cross-section bars. The current work concerns an Enhanced Textured Powder (ETP) process, in which silver nanopowder is homogeneously mixed with the Bi-2212 powder. We report studies of the effect of the addition on the phase dynamics near melt temperature. ETP cores are being prepared for compounding into a billet to fabricate multi-filament wire.

	The strong-focusing cyclotron is a high-current proton/ion accelerator in which superconducting rf cavities are used to provide enough energy gain per turn to fully separate orbits, and arc-shaped beam transport channels are located in the sector dipole aperture to provide strong focusing of all orbits. An optimization method has been devised by which the orbit separations can be adjusted to provide sufficient separation while maintaining isochronicity on all orbits. The transport optics of the FD lattice is also optimized to provide stable transport and to lock the betatron tunes to a favorable value over the full range of acceleration.

The strong-focusing cyclotron is a high-current proton/ion accelerator in which superconducting rf cavities are used to provide enough energy gain per turn to fully separate orbits, and arc-shaped beam transport channels are located in the sector dipole aperture to provide strong focusing of all orbits. An optimization method has been devised by which the orbit separations can be adjusted to provide sufficient separation while maintaining isochronicity on all orbits. The transport optics of the FD lattice is also optimized to provide stable transport and to lock the betatron tunes to a favorable value over the full range of acceleration.
