专门的电偶极矩（edm）的搜索已经完成，只有中性系统。我们在这次演讲中讨论了测量带电粒子edm的专用存储环建议。中子和汞原子edm搜索的统计误差超过系统误差。今天，在几个加速器上，可以从现代极化源获得大量粒子。在BNL进行的一项拟议的质子电火花加工实验将使目前的质子电火花加工极限提高104倍。德国尤利希COSY提出了一个“前体”氘核电火花加工实验。这将是第一次测量氘核edm。
Dedicated electric dipole moment (edm) searches have been done only for neutral systems. We discuss in this talk dedicated storage ring proposals for measuring edms of charged particles. The statistical error dominates over the systematic error for the neutron and mercury atom edm searches. Large numbers of particles are available today from modern polarized sources at several accelerators. A proposed proton edm experiment at BNL would improve the present proton edm limit by a factor of 104. A "precursor" deuteron edm experiment has been proposed at COSY, Juelich, Germany. This would be the first measurement of the deuteron edm.
