论文摘要

在寻找轴突暗物质时,基于空腔的吊带板为微波区域中理论上有趣的模型提供了最敏感的方法。但是,实验搜索仅限于相对较低的质量,最高几十$ $ $ eV,这受益于给定实验设置的大型检测量和高质量因素。我们提出了一种适用于具有增强性能的较高质量区域的新型腔设计。该设计的特征是在常规导电腔中定期布置介电材料,在该腔中,谐振频率由空间确定。即使在高频下,这种光子晶体卤代型也可以充分利用给定的体积,同时实质上改善了腔质量因子。考虑使用辅助结构来部署阵列以进行二维频率调整。我们介绍了这种卤素设计的特征,并证明了其对高质量斧头搜索的可行性。

In the search for axion dark matter, the cavity-based haloscope offers the most sensitive approach to the theoretically interesting models in the microwave region. However, experimental searches have been limited to relatively low masses up to a few tens of $μ$eV, benefiting from large detection volumes and high quality factors for a given experimental setup. We propose a new cavity design suitable for axion searches in higher mass regions with enhanced performance. The design features a periodic arrangement of dielectric material in a conventional conducting cavity where the resonant frequency is determined by the interspace. This photonic crystal haloscope can make full use of a given volume even at high frequencies while substantially improving the cavity quality factor. An auxetic structure is considered to deploy the array for two-dimensional frequency tuning. We present the characteristics of this haloscope design and demonstrate its feasibility for high-mass axion searches.
