用于HAYSTAC暗物质轴子研究的对称多棒可调谐微波腔
A Symmetric Multi-rod Tunable Microwave Cavity for the HAYSTAC Dark Matter Axion Search
摘要：
微波腔实验是在0.1-10 GHz范围内寻找轴子的最灵敏的方法，对应于0.5 - 40 $μ$ eV的质量。对于大于5GHz的频率的特定挑战是设计具有大体积的腔，该腔包含具有高形状因子、高品质因数、宽动态范围并且没有入侵模式的谐振模式。对于HAYSTAC，我们设计并构建了一个优化的高频腔，该腔具有保持高度旋转对称性的调谐机制，这对于最大化其品质因数至关重要。根据最近对轴子质量5.5 - 7.4 GHz的理论估计，该腔覆盖了一个重要的频率范围，并且该设计似乎也可扩展到更高的频率。本文将讨论关键的设计和施工细节的腔，提出了一个总结的设计演变，并提醒从业人员的潜在的徒劳的途径，为今后的工作。
英文摘要：
The microwave cavity experiment is the most sensitive way of looking for axions in the 0.1-10 GHz range, corresponding to masses of 0.5 - 40 $μ$eV. The particular challenge for frequencies greater than 5 GHz is designing a cavity with a large volume that contains a resonant mode that has a high form factor, a high quality factor, a wide dynamic range, and is free from intruder modes. For HAYSTAC, we have designed and constructed an optimized high frequency cavity with a tuning mechanism that preserves a high degree of rotational symmetry, critical to maximizing its figure of merit. This cavity covers an important frequency range according to recent theoretical estimates for the axion mass, 5.5 - 7.4 GHz, and the design appears extendable to higher frequencies as well. This paper will discuss key design and construction details of the cavity, present a summary of the design evolution, and alert practitioners of potentially unfruitful avenues for future work.
