A new method has been developed to search for an electric-dipole moment of the electron using atomic cesium, and a factor of twenty improvement has been realized. With increased cesium density a further order of magnitude is anticipated, and another order of magnitude will be pursued by use of additional and improved cesium cells. If successful the project should generate the most stringent experimental limits on theoretical models that attempt to understand violations of time-reversal invariance.

开发了一种使用原子铯来寻找电子电偶极矩的新方法，并且已经实现了二十倍的改进。 随着铯密度的增加，预计会再增加一个数量级，并且将通过使用额外的和改进的铯电池来追求另一个数量级。 如果成功，该项目应该对试图理解时间反转不变性的违反的理论模型产生最严格的实验限制。
