论文摘要
无形的轴轴是一个动机良好的假设粒子，可以解决现代物理学中的两个基本问题 - 强烈互动中的CP对称问题和我们宇宙的暗物质神秘。 QCD轴作为暗物质候选者的合理质量（频率）范围从UEV到MEV（O（GHz）到O（THz））。使用谐振腔的轴突悬挂仪在微波区域提供了最敏感的搜索方法。但是，实验搜索的质量区域限制为相对较低，这主要是由于高质量下的腔体积减少。作为用于高质量轴搜索的有效方法，提出并成功证明了一个独特的腔设计，由单个圆柱形腔中的多个相同的单元用等距的薄金属隔板划分。我们进行了一项深入的研究，以表征多细胞腔设计，并讨论它为高质量斧头搜索提供的各种优势。
The invisible axion is a well-motivated hypothetical particle which could address two fundamental questions in modern physics - the CP symmetry problem in the strong interactions and the dark matter mystery of our universe. The plausible mass (frequency) range of the QCD axion as a dark matter candidate spans from ueV to meV (O(GHz) to O(THz)). The axion haloscope using a resonant cavity has provided the most sensitive search method in the microwave region. However, experimental searches have been limited to relatively low mass regions mainly due to the reduced cavity volume at high masses. As an effective approach for high-mass axion searches, a unique cavity design, featured by multiple identical cells divided by equidistant thin metal partitions in a single cylindrical cavity, was proposed and successfully demonstrated. We perform an in-depth study to characterize the multiple-cell cavity design and discuss the various advantages it offers for high-mass axion searches.
