论文摘要
搜索暗物质轴涉及在强磁场中使用的微波谐振腔。检测器敏感性与腔质量因子直接相关，但是，由于外部磁场的存在而受到限制。在本文中，我们提出了一种新型设计的空腔，其质量因子不受磁场的影响。它是基于光子结构，它通过使用蓝宝石棒。低温温度下的质量因子超过$ 5 \ times 10^5 $，对于选定的模式。
Searches for dark matter axion involve the use of microwave resonant cavities operating in a strong magnetic field. Detector sensitivity is directly related to the cavity quality factor, which is limited, however, by the presence of the external magnetic field. In this paper we present a cavity of novel design whose quality factor is not affected by a magnetic field. It is based on a photonic structure by the use of sapphire rods. The quality factor at cryogenic temperature is in excess of $5 \times 10^5$ for a selected mode.
