Abstract
A septum magnet includes a yoke that can be separated at the approximately center portion thereof in the axis direction; a septum coil; a return coil; and a vacuum duct that is inserted between the septum coil and the return coil. The septum coil is formed in such a way as to be able to be separated into a first portion and a second portion in response to separation of the yoke; and in a space between the septum coil and the vacuum duct, there is provided an auxiliary coil, in two portions of which, corresponding to the first portion and the second portion of the septum coil, electric currents flow in opposite direction to each other in a circumferential direction.
