Description
Tube type Nb3Sn conductor has been being explored by Hyper Tech Research Inc. Our standard conductor with 217 filament arrays have been generated with 12 T non-Cu Jc values of about 2400-2500 A/mm2 with filament size of 40 micros at the 0.85 mm strand. We also made 547 filament conductor which has filament size of 25 micros at the 0.85 mm strand without any drawing issue. This conductor exhibited no fabrication problems and was drawn down and tested at a small diameter wire. The standard strand has been successfully applied on the fabrication of helical and planar undulator, both of which reach the fields that are expected in the ILC and Light source industry. It has also been tried in small magnet and the related information will be presented. We are working to improve the non-Cu Jc further by creating artificial pinning centers in the strand which will be presented in this paper.
