A new muon g–2/EDM experiment at J-PARC (E34) is under preparation in order to resolve a 3 sigma discrepancy of muon anomalous magnetic dipole moment between the measurement and the standard model prediction. The E34 experiment will employ a unique three-dimensional spiral injection scheme in order to store the muon beam into a small storage orbit. In order to demonstrate the feasibility of novel injection scheme, the Spiral Injection Test Experiment (SITE) with the electron beam is under construction at KEK Tsukuba campus. The goals of the SITE are divided into two phases. In SITE, 80 keV DC electron beam was injected at forty degree into the storage magnet, and detected as a fluorescent light due to the de-excitation of the nitrogen gas. The pulsed electron beam, and a pulsed magnetic kicker are developed in order to keep the pulsed beam to the very center of the storage magnet. The magnetic kicker mainly produced the radial field to reduce the pitch angle of the injected beam to keep the beam at storage region. In this poster, the development of magnetic kicker for the STE is presented.
