A novel pulse septum magnet for the injection system of NSRL storage ring which is a dedicated synchrotron radiation facility was described in this paper. The main parameters and measured results of the septum including its magnetic ®eld distribution and its vacuum characteristic were given also. After making a shim the stray ®eld near current strip to gap magnetic ®eld was reduced to 0.1%, and the pressure of the vacuum chamber, in which the septum magnet was installed, is less than 510 10
