摘要：
对囚禁的反氢原子（$\overline{\text{H}}$）和氢原子（$\text{H}$）进行高精度光谱比较，有望严格检验粒子物理标准模型的基本CPT对称性不变性。ATRAP的嵌套彭宁-约费阱正是为这类研究而开发。其独特特征之一是，用于$\overline{\text{H}}$原子的磁约费阱可在四极对称和八极对称之间切换。其独特特征之二是，它允许激光和微波沿垂直于阱中心轴的方向进入。
英文摘要：
High-accuracy spectroscopic comparisons of trapped antihydrogen atoms ($\overline{\text{H}}$) and hydrogen atoms ($\text{H}$) promise to stringently test the fundamental CPT symmetry invariance of the standard model of particle physics. ATRAP's nested Penning-Ioffe trap was developed for such studies. The first of its unique features is that its magnetic Ioffe trap for $\overline{\text{H}}$ atoms can be switched between quadrupole and octupole symmetries. The second is that it allows laser and microwave access perpendicular to the central axis of the traps.
