The low-beta insertion quadrupoles are iron-free superconducting magnets with an inner coil diameter of 140 mm, an effective length of 1.14 m, and a nominal gradient of 70 T/m. The coils, which are of cos 2 {Theta} type, are made from four layers of 27-strand NbTi Rutherford-type cable with Kapton insulation and are firmly clamped with 316LN stainless steel collars. Following the development of prototype magnets at KEK, eight magnets have been produced by industry and were thoroughly tested and measured at KEK prior to installation in the TRISTAN main ring. In this paper, a brief description of the design and manufacturing technique as well as the results of tests and measurements are presented.
