  The first FCC-ee final focus quadru­pole pro­to­type has been de­signed, man­u­fac­tured, as­sem­bled and tested at warm. The pro­to­type is a sin­gle aper­ture quadru­pole mag­net of the CCT type. One edge of the mag­net was de­signed with local mul­ti­pole can­cel­la­tion, whereas the other was left with the con­ven­tional de­sign. An op­ti­mized ro­tat­ing in­duc­tion-coil sen­sor was used. A tech­nique was de­vel­oped to take into ac­count field dis­tor­tions due to the en­vi­ron­ment of the test and dis­tin­guish them from mag­net ef­fects, demon­strat­ing an ex­cel­lent field qual­ity for the pro­to­type.
