  A single aperture Canted-Cosine-Theta (CCT) quadrupole magnet, made of NbTi
superconductors, has been developed for the final focus region of the FCC-ee
study. The conductor layout is optimised to mitigate edge effects on one of the
two sides of the magnet that typically lead to undesired higher-order
multipoles. Experimental results of a prototype, including paraffin wax
impregnation and cryogenic temperature measurements, are presented. The magnet
exhibits no training behaviour, surpassing the nominal current during the
initial ramp. Field quality is excellent, with higher-order multipoles below
$1\times 10^{-4}$ units, consistent with simulations and room temperature
tests. These findings confirm the potential of superconducting CCT magnets to
offer compact solutions for applications demanding stringent field quality.
