Analysis of single-photon and linear amplifier detectors for microwave cavity dark matter axion searches

S. K. Lamoreaux, K. A. van Bibber, K. W. Lehnert, G. Carosi

摘要:

我们表明,在较高的频率,从而更高的轴子质量,单光子探测器变得有竞争力,并最终青睐,量子限制线性放大器相比,作为探测器技术在微波腔实验搜索星系晕暗物质轴子。在该比较中的交叉点是10 GHz($\sim 40\ μ$ eV)量级,并不远高于当前搜索的频率。

英文摘要:

We show that at higher frequencies, and thus higher axion masses, single-photon detectors become competitive and ultimately favored, when compared to quantum-limited linear amplifiers, as the detector technology in microwave cavity experimental searches for galactic halo dark matter axions. The cross-over point in this comparison is of order 10 GHz ($\sim 40\ μ$eV), not far above the frequencies of current searches.
