论文摘要
斧头是一种流行的暗物质候选者,通常在称为``haloscopes''的实验中搜索,它可以利用推定的轴突 - 光子耦合。这些实验通常依赖于谐振的横向磁(TM)模式(TM)模式,以捕获和检测到通过轴向转换量的pection量捕获和检测轴向对转换的搜索量。我们呈现轴承量的量。搜索(尤其是$ \ sim $ 60 $ \,μ$ ev)。提出了敏感性(DBA)的谐振器。
Axions are a popular dark matter candidate which are often searched for in experiments known as ``haloscopes" which exploit a putative axion-photon coupling. These experiments typically rely on Transverse Magnetic (TM) modes in resonant cavities to capture and detect photons generated via axion conversion. We present a study of a resonant cavity design for application in haloscope searches, of particular use in the push to higher mass axion searches (above $\sim$60$\,μ$eV). In particular, we take advantage of azimuthally varying TM$_{m10}$ modes which, whilst typically insensitive to axions due to field non-uniformity, can be made axion-sensitive (and frequency tunable) through strategic placement of dielectric wedges, becoming a type of resonator known as a Dielectric Boosted Axion Sensitivity (DBAS) resonator. Results from finite-element modelling are presented, and compared with a simple proof-of-concept experiment. The results show a significant increase in axion sensitivity for these DBAS resonators over their empty cavity counterparts, and high potential for application in high mass axion searches when benchmarked against simpler, more traditional designs relying on fundamental TM modes.
