论文摘要
冷分子核时间反转实验（CENTREX）是一项新的努力，旨在显着提高敏感性，而不是违反基本相互作用的HADRONIC TIME RESSSAL（$ t $）强度的最佳当前上限。实验签名将是$^{205} $ tl的核磁共振频率的变化，在电偏氟化硫化硫化硫化硫化物（TLF）分子中。在这里，我们描述了研究这些$ t $略有互动的动机，并使用TLF来进行此功能。为了达到比早期在TLF中搜索$ t $侵略的敏感性，Centrex使用低温分子束源，光学状态制备和检测以及相干量子状态操作的现代方法。介绍了测量方案和设备的当前状态的细节，并进行了TLF梁的定量测量。最后，讨论了控制系统错误的估计灵敏度和方法。
The Cold molecule Nuclear Time-Reversal EXperiment (CeNTREX) is a new effort aiming for a significant increase in sensitivity over the best present upper bounds on the strength of hadronic time reversal ($T$) violating fundamental interactions. The experimental signature will be shifts in nuclear magnetic resonance frequencies of $^{205}$Tl in electrically-polarized thallium fluoride (TlF) molecules. Here we describe the motivation for studying these $T$-violating interactions and for using TlF to do so. To achieve higher sensitivity than earlier searches for $T$-violation in TlF, CeNTREX uses a cryogenic molecular beam source, optical state preparation and detection, and modern methods of coherent quantum state manipulation. Details of the measurement scheme and the current state of the apparatus are presented, with quantitative measurements of the TlF beam. Finally, the estimated sensitivity and methods to control systematic errors are discussed.
