In this paper, a reflection magnet to be installed in the EAST neutral beam injection system is simulated and designed. The field intensity of reflection magnet of 42-cm maximum bending radius is about 1.539×10–1 T for 100 keV deuterium beam. The shielding cage is formed by rods. Using the ANSOFT software, the magnetic shielding effect was estimated at about 3% at the magnet pole region.
