Introduction Newly fabricated water-cooled coils of sextupole magnets were tested by measuring magnetic field using Hall probe bench. The probe is 3-axis MMZ-2536-UH Gaussmeter Hall probe from Lake Shore Cryotronics, Inc. Cross-section of the SF-type sextupole magnet is shown in Figure 1 with the magnet physical length of 150 mm. For SD-type magnet, the magnetic poles are opposite to the poles of the SF magnet and the physical length is 200 mm. Design parameters of both magnets are listed in Table 1. Also shown in the table is correcting coils information. The coils are wound on top of the sextupole coils to provide correction and possibility to generate skew-quadrupole field.
