Abstract :
In order to obtain a high-intensity neutron beam for neutron scattering experiments, strong sextupole magnets with large apertures are useful as a focusing element. We have started the development of a Nb3Sn sextupole magnet for this purpose. The design field strength of the sextupole is 12780 T/m2 and the aperture of the coil is 46 mm in diameter. As a first step of the development, three model coils have been made in order to learn about Nb3Sn technology and to evaluate the fabrication techniques. Single-pole tests of these coils have been performed to assess the conductor stability and training behavior of the Nb3Sn coils. This paper describes the design of the magnet, the fabrication of the model coils and the results of single-pole tests
