Abstract

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 field distribution and its vacuum characteristic were given also. After making a shim the stray field near current strip to gap magnetic field was reduced to 0.1%, and the pressure of the vacuum chamber, in which the septum magnet was installed, is less than 5×10^-10 mbar after baking. Now the septum magnet is playing an important part in getting a high injection efficiency and high accumulating current in the NSRL storage ring during the machine running
