研制了两种不同尺寸的光子晶体结构腔，用于轴子搜索。在腔中，利用了光子晶体中的色散关系，因此被命名为“DRiPC腔”。较小的一个尺寸为100 mm x 100 mm x 10 mm，其中16个直径为4 mm的圆柱形金属杆以20 mm的间隔引入4x 4网格中。在这项研究中，在小尺寸的腔体，Lx，在x方向上的网格间隔被改变，以调查谐振频率，Q值，和电场分布在每个Lx。最低的三个频率进行了比较，通过有限元方法模拟的，发现在良好的协议。最低频率模式可以从5.10 GHz（Lx = 25.0 mm）调谐到6.72 GHz（13.9 mm），在Lx = 20 mm时以5.87 GHz为中心。这种宽范围的可调谐性（27.7%）适合于具有适度Q值的搜索。通过用珠拉法研究电场分布，在Lx = 16.0 - 25.0 mm处的最低频率模式为类TM 010模式。在具有相同光子晶体结构的较大尺寸腔（180 mm x 180 mm x 20 mm x 2）中也获得了该模式。这些结果使我们得出结论，DRiPC腔具有未来轴子搜索实验的高贵特征。
英文摘要：
Two cavities in different size with the photonic crystal structure have been developed for axion searches. In the cavities, the dispersion relation in the photonic crystal is utilised, and so was named to "DRiPC cavities". The size of the smaller one is 100 mm x 100 mm x 10 mm, where 16 cylindrical metal poles with a diameter of 4 mm are introduced in a 4x4 grid at 20 mm intervals. In this study, the grid interval in x direction in the small size cavity, Lx, was changed to investigate resonance frequency, Q-value, and electric field profile at each Lx. The lowest three frequencies have been compared with the ones simulated by the finite element method to be found in excellent agreement. The lowest frequency mode could be tuned from 5.10 GHz (Lx = 25.0 mm) to 6.72 GHz (13.9 mm), centering on 5.87 GHz at Lx = 20 mm. This wide range tunability, 27.7%, was suitable for a search with a modest Q-value. By examining the electric field distributions with the bead pull method, the lowest frequency mode at Lx = 16.0 - 25.0 mm were TM010-like. This mode was also obtained in a larger size cavity (180 mm x 180 mm x 20 mm x 2) with the same photonic crystal structure. These results led us to conclude a DRiPC cavity has the noble features for future axion search experiments.

遗迹轴子探测器实验装置（RADES）是一个轴子搜索项目，使用微波滤波器作为暗物质转换的谐振器。本出版物的主要重点是描述3种不同的腔原型的RADES。的原型之一的第一次测试的结果也被提出。过滤器由5或6个不锈钢子腔组成，由矩形膜片连接。子腔的大小决定了工作频率，子腔的数量决定了工作体积。第一个腔原型于2017年建造，工作频率为$\sim$ 8.4 GHz，并放置在CERN的9 T CAST偶极磁体上。2018年又设计并建造了两个原型。新设计的目的是找到并测试最佳腔体几何形状，以便按比例放大体积并引入有效的调谐机制。我们的研究结果表明，这种类型的过滤器，以达到QCD轴子在X波段的频率灵敏度有前途的潜力。
