Abstract

The septum magnet bends the injection beam before the kicker magnet. The septum magnet is located near the storage ring in the Taiwan Photon Source (TPS). As the space from the magnet wall to the vacuum chamber of the ring is less than 3 mm, the leakage field of the septum magnet thus influences the stability of the electron beam in the storage ring. The main field and the leakage field of a septum of the direct-drive type are compared to one of the eddy-current type. The effects of the vacuum chamber and μ-metal are simulated with full-sine and half-sine current pulses with the OPERA-2D TR analysis module; measurement results are presented in this paper.
