Abstract
The development of a vertical kicker system is an important part of a three-dimensional spiral-injection scheme. The beam injected at a pitch angle of a few tens of degrees was controlled by applying a pulsed magnetic field using a vertical kicker system inside the storage magnet. The stored muon beam then followed a vertical betatron motion around the midplane of the storage magnet owing to the weak focusing magnetic field. Accurate control of the pulsed kick is crucial for minimizing the amplitude of the vertical betatron oscillation. The specifications of the pulsed magnetic field and detailed design of the kicker system at the test beam bench are discussed herein.
