论文摘要
α磁陷阱中的抗氧抗原子持续多长时间是α设备的重要特征。在2010年[1]进行了最初的捕获实验，并用38个被检测到的抗体限制为172 ms，并在2011年[2]中以1000 s的速度进行了7个。在光谱测量过程中进行详细的频率扫描是必需的。使用机器学习方法进行的分析，对alpha-2磁陷阱中限制几个小时的1000多个抗原进行了分析，该分析对66小时的寿命产生了初步的下限。因此，该观察结果表明，测得的抗溶毒的限制时间延长了两个以上的数量级。 [1] Andresen，G。B.等。 （Alpha合作），Nature 468，673-676（2010） [2] Andresen，G。B.等。 （Alpha协作），自然物理。 7，558-564（2011）
How long antihydrogen atoms linger in the ALPHA magnetic trap is an important characteristic of the ALPHA apparatus. The initial trapping experiments in 2010 [1] were conducted with 38 detected antiatoms confined for 172 ms and in 2011 [2] with seven for 1000 s. Long confinement times are necessary to perform detailed frequency scans during spectroscopic measurements. An analysis carried out, using machine learning methods, on more than 1000 antiatoms confined for several hours in the ALPHA-2 magnetic trap, yields a preliminary lower limit to the lifetime of 66 hours. Hence this observation suggests that the measured confinement time of antihydrogen is extended by more than two orders of magnitude. [1] Andresen, G. B. et al.
