论文摘要
已经部署了微波炉,以搜索质量为几美元$ $ EV的玻色粒暗物质候选者。但是,这些空腔探测器的敏感性受其体积的限制,传统的半波长腔体在较高的质量下的体积降低显着降低。 ADMX-ORPHEUS通过在高阶模式下操作可调的,介电的腔,从而减轻此问题,从而使检测量保持较大。 ADMX-ORPHEUS首发运行不包括深色光子暗物质,具有动力学混合角$χ> 10^{ - 13} $之间的65.5 $μ$ eV(15.8 GHz)和69.3 $μ$ ev(16.8GHz),标志着最高功能的Microwable Microwable Microwable Dark cavity dark cavity dearkity dearkity with at at Date。
Microwave cavities have been deployed to search for bosonic dark matter candidates with masses of a few $μ$eV. However, the sensitivity of these cavity detectors is limited by their volume, and the traditionally-employed half-wavelength cavities suffer from a significant volume reduction at higher masses. ADMX-Orpheus mitigates this issue by operating a tunable, dielectrically-loaded cavity at a higher-order mode, which allows the detection volume to remain large. The ADMX-Orpheus inaugural run excludes dark photon dark matter with kinetic mixing angle $χ> 10^{-13}$ between 65.5 $μ$eV (15.8 GHz) and 69.3 $μ$eV (16.8GHz), marking the highest-frequency tunable microwave cavity dark matter search to date.
