Abstract :
Within the framework of a collaboration with IHEP for the UNK project, two test stands have been built and delivered to measure the magnetic characteristics of the UNK superconducting quadrupoles: location and transfer of the magnetic axis, gradient value, and homogeneity. The authors describe the different parts of the apparatus, in particular the carbon-fiber measuring tube which enables the sag of the measuring devices to be minimized. Emphasis is placed on the mechanical measurements and controls made on the measuring tube, the wire system used to locate the magnetic axis, and the optical elements selected for the alignment. Preliminary results obtained in the USSR are reported
