An iron septum magnet was designed for the charged-particle beam splitting system. Magnetic field measurements of the septum model magnet with a circular hole were performed for several conditions. The hole field is B0 = 60–250 G for a hole radius of 12 mm and the gap field is Bg = 5–6 kG for a gap distance of 8 mm with a septum thickness of 1 mm. The multipole field strength in the circular hole is obtained from the field distribution.
