Development and Test of Nb3Sn Cos-Theta Dipoles Based on PIT Strands.

Fermilab is involved in the development of new generation high-field accelerator magnets using state-of-the-art Nb₃Sn strands produced using different technologies. Two 1-m long models—mirror configuration and dipole magnet—were fabricated recently at Fermilab based on powder-in-tube (PIT) Nb₃Sn strands with small effective filament size. This paper describes the parameters of superconducting strands and cable, the details of magnet design and fabrication procedure, and reports the results of PIT coil testing. [ABSTRACT FROM AUTHOR]
