Abstract

A new experiment at J-PARC (E34) is under construction to measure the muon's g – 2 to unprecedented precision of 0.1 ppm and electric dipole moment up to the sensitivity of 10–21 e.cm in order to explore new physics beyond the standard model. A novel three-dimensional spiral injection scheme has been devised to inject and store the beam into a small diameter MRI-type storage magnet for E34. The new injection scheme features smooth injection with high storage efficiency for the compact magnet. However, spiral injection scheme is an unproven idea, therefore, a Spiral Injection Test Experiment (SITE) at KEK Tsukuba Campus is underway to establish this injection scheme. SITE consists of a 80keV thermionic electron gun, two-meter-long beamline, and a solenoid storage magnet. The DC electron beam spiral track has been confirmed by the de-excitation of the nitrogen gas in the vacuum chamber of the storage magnet. A new wire scanner system has been developed to extract the beam current, profile and geometrical information of three-dimensional trajectory.
