项目摘要
The origin of CP violation, which was discovered in particle decay and is considered to be one of sources for matter-antimatter asymmetry in universe, is one of important objectives in modern physics. In order to search for atomic EDM violating CP symmetry, the research and development have been conducted for ultra-high precision measurement of nuclear spin precession of 129Xe. The various fluctuations to the spin system have been investigated, high sensitivity magnetometer have been developed, leading to improvement of frequency stability for low-frequency nuclear spin oscillator. The sensitivity of 5×10-28 ecm for atomic EDM of 129Xe has been achieved (with a measurement time of 45,000 s) assuming the electric field strength of 10 kV/cm.
CP违规的起源是在粒子衰减中发现的,被认为是宇宙中物质抗对称不对称的来源之一,是现代物理学中的重要目标之一。为了搜索违反CP症状的原子EDM,已经进行了研究和开发,以超高精度测量129xE的核旋转预防。已经研究了对自旋系统的各种波动,已经开发出高灵敏度磁力计,从而改善了低频核自旋振荡器的频率稳定性。假设电场强度为10 kV/cm,已经达到了5×10-28 ECM对原子EDM的敏感性(测量时间为45,000 s)。
