一个新的实验正在J-PARC （E34）进行，以测量μ子的g - 2，其精度达到前所未有的0.1 ppm，电偶极矩的灵敏度达到10-21 e.cm，以探索超越标准模型的新物理。设计了一种新颖的三维螺旋注入方案，将光束注入并存储在E34的小直径mri型存储磁体中。新的注入方案具有平滑注入和高存储效率的紧凑磁铁。然而，螺旋注射方案是一个未经证实的想法，因此，KEK筑波校区的螺旋注射测试实验（SITE）正在进行中，以建立这种注射方案。SITE由一个80keV的热电子枪、两米长的光束线和一个电磁存储磁铁组成。通过对存储磁体真空室中氮气的去激发，证实了直流电子束的螺旋轨迹。开发了一种新的线扫描系统，用于提取三维轨迹的光束电流、轮廓和几何信息。
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.
