Sn-Ta-Cu buttons with enough ductility to be fabricated into thin sheets were synthesized by melting a mixture of Sn+Ta+(Cu) powder. (Nb,Ta)/sub 3/Sn wires have been prepared by a Jelly Roll (JR) process and a filamentary process. In the JR process a

Fabrication of High-Field (Nb,Ta)3Sn Conductors Through a Jelly Roll Process

Autor: T. Koyata, K. Watanabe, Kyoji Tachikawa, Hiroyuki Izawa, T. Takeuchi, Yuuya Ikeda

Publikováno v: AIP Conference Proceedings.

Fabrication and high‐field performance of (Nb,Ta)3Sn conductors through a new Jelly Roll process using Sn‐Ta sheet are reported. A mixed powder of Sn and Ta (Ta/Sn ratio=3/7 and 1/3) with or without a small amount of Cu addition was melted at 800
