Abstract：
The physics design of BEPCⅡ storage ring requires that the kicker magnets must have properties of wide uniform field region with high field uniformity and low beam impedance. In order to satisfy these requirements, a new slotted pipe kicker magnet is proposed. The results from theoretical analysis and OPERA program simulation show that the kicker magnet satisfies all requirements of BEPCⅡ storage ring. In the range of Δx=±20mm, the field uniformity is ±0.6% in the central plane, ±0.7% in the y=5mm plane and ±2.9% in the y=10mm plane. The simulated results of MAFIA program also show that the beam impedance of the kicker magnet is lower than 0.022Ω, and it is less than the required value of 0.025Ω.
