论文摘要
我们报告了有关隐藏光子暗物质存在的方向检测约束，其中使用低温发射器 - 放大器 - 放大器谱图设置在20-30 UEV之间，设计为Qualiphide的第一次迭代（在黑暗实验中量子有限的光子）。从隐藏的光子动力学混合到喇叭天线的金属碟源转换光子，该光子与C波段动力电感循环行动波参数放大器耦合，提供了接近量子限制的噪声性能。我们证明了该区域中大多数隐藏光子质量的动力学混合参数“ CHI”的首次探测到略高于10^-12。这些结果不仅代表了对新的暗物质参数空间的严格约束，而且也是首次证明使用宽带量子限制的放大的肌肉粒子应用程序
We report direction detection constraints on the presence of hidden photon dark matter with masses between 20-30 ueV using a cryogenic emitter-receiver-amplifier spectroscopy setup designed as the first iteration of QUALIPHIDE (QUantum LImited PHotons In the Dark Experiment). A metallic dish sources conversion photons from hidden photon kinetic mixing onto a horn antenna which is coupled to a C-band kinetic inductance traveling wave parametric amplifier, providing for near quantum-limited noise performance. We demonstrate a first probing of the kinetic mixing parameter "chi" to just above 10^-12 for the majority of hidden photon masses in this region. These results not only represent stringent constraints on new dark matter parameter space but are also the first demonstrated use of wideband quantum-limited amplification for astroparticle applications
