Abstract

A model of a quadrupole magnet for linear accelerators was designed, fabricated, and tested at KEK in order to gain fabrication experience and a better understanding of superconducting magnet characteristics. The assembly has a design field gradient of 56.5 T/m, an aperture of 92 mm, and a cold mass length of 680 mm. Furthermore, it is designed as a superferric magnet with four racetrack coils wound with a specially fabricated ribbon cable of eight superconducting strands. In this paper, we present details of the magnet design, fabrication, and the results of its cold tests. Data of the field measurements are also presented in brief.
