摘要
SIDDHARTA-2代表一项最先进的实验，旨在对奇异原子（由带负电的K介子与原子核组成的特殊奇异原子构型）进行专用测量。研究这些原子为理解涉及奇异数的非微扰区强相互作用提供了绝佳工具。该实验安装在意大利INFN弗拉斯卡蒂国家实验室（INFN-LNF）的DAΦNE电子-正电子对撞机上，旨在首次测量奇异氘原子中的2p→1s X射线跃迁，这是确定同位旋依赖的反K介子-核子散射长度的关键一步。基于先前SIDDHARTA实验（其完成了最精确的奇异氢原子2p→1s X射线跃迁测量）所获经验，本装置已通过创新的硅漂移探测器（SDDs）升级，这些探测器分布在置于真空室中、距对撞机相互作用区上方短距离处的低温气体靶周围。我们给出了SIDDHARTA-2装置的全面描述，包括在对撞机调试阶段各组件的优化。
