This proposal is for the continuation of a search for an electron electric dipole (EDM) moment using a high precision cesium magnetometer. The existence of an EDM in cesium would indicate a violation of the principle of time-reversal invariance (T). Thus far, only one violation of T is known, the K-meson system. The discovery of a new system that violates T could allow one to determine which of the many theories that describe this violation is correct. The proposal also seeks to continue the development of a new experimental that tests Einstein's postulate of local Lorentz Invariance by comparing the frequencies of magnetometers as the earth rotates.

这项提议是为了继续使用高精度铯磁强计寻找电子电偶极子(EDM)矩。铯中电火花的存在表明违反了时间反转不变性(T)原理。到目前为止，只有一种T的破坏是已知的，那就是K介子系统。一个违反T的新系统的发现可能使人们能够确定描述这种违反的众多理论中的哪一个是正确的。该提案还寻求继续发展一项新的实验，通过比较地球自转时磁力计的频率来测试爱因斯坦的局部洛伦兹不变性假设。
