AI总结：
本文提出两种射频腔配置（相邻与嵌套）探测暗光子，证明嵌套配置在TM010模式下灵敏度更高，而TE011模式下两者相当。
摘要：
我们研究了用于探测暗光子的射频（RF）腔实验，该实验是对光穿薄壁（LSthinW）装置的改进，在圆柱形发射器和中空接收器之间设置了一个相对较薄的导电屏障。该实验设施能够有效探测暗光子，即使是在离壳（off-shell）区域，即当暗光子质量超过发射器腔体的驱动频率时，该腔体由电磁模式泵浦。\n我们比较了两种特定装置配置的灵敏度：（i）两个相邻的圆柱形腔体端对端放置，并由端盖分隔；（ii）一种嵌套几何结构，其中圆柱形接收器被封装在发射器内部。我们证明，对于一定范围的暗光子质量，采用TM010泵浦模式的嵌套配置相比相邻发射器配置可以提供更高的灵敏度。\n值得注意的是，对于TE011泵浦模式，嵌套和相邻腔体配置在特定几何类型下均可产生相当的预期探测范围。

We address the radio frequency (RF) cavity experiment for probing dark photons, which is a modification of the light-shining-through-thin-wall (LSthinW) setup with a relatively thin conducting barrier between cylindrical emitter and hollow We address the radio frequency (RF) cavity experiment for probing dark photons, which is a modification of the light-shining-through-thin-wall (LSthinW) setup with a relatively thin conducting barrier between a cylindrical emitter and a hollow receiver. The experimental facility allows for the effective probing of dark photons even in the off-shell regime, i.e., when the dark photon mass exceeds the driving frequency of the emitter cavity, which is pumped by an electromagnetic mode. We compare the sensitivity of two specific setup configurations: (i) two adjacent cylindrical cavities placed end-to-end with an end-cap separating them, and (ii) a nested geometry in which the cylindrical receiver is encapsulated within the emitter. We demonstrate that, for a certain range of dark photon masses, the nested configuration with the $\mbox{TM}_{010}$ pump mode can provide enhanced sensitivity compared to an adjacent emitter setup. Remarkably, for the $\mbox{TE}_{011}$ pump mode, both the nested and adjacent cavity configurations can yield comparable expected reaches for the specific geometry type.
