Zusammenfassung:	Oxford Superconducting Technology (OST) produces Nb/sub 3/Sn superconductive composites via several different fabrication methods. We report here some aspect of improvements made in these products. Enhancement in very high field properties have been introduced for bronze processed composite using Nb filaments with Ta addition and bronze matrix with Ti addition. In modified jelly roll (MJR) composite non-copper critical current density has been improved to over 3000 A/mm/sup 2/ at 10T by modifying design. This performance is reproduced routinely in production.
