用于暗物质探测的GHz超导单光子探测器

GHz Superconducting Single-Photon Detectors for Dark Matter Search

Federico Paolucci, Francesco Giazotto

摘要:

暗物质的组成是天体物理学中令人困惑的课题之一。为了解决这个问题,在过去的二十年里,已经设计、建造和实现了几个寻找轴子存在的实验。在所有其他实验中,光透过墙壁的实验有望将排斥极限推向更低的能量。为此,致力于开发工作在$<100$ GHz频率的单光子探测器。在这里,我们回顾了超导单光子探测的最新进展。特别是,我们提出了两个传感器的基础上,一维约瑟夫森结的能力,在原位调整简单的电流偏置:纳米级的过渡边缘传感器(纳米TES)和约瑟夫森逃逸传感器(JES)。这两种传感器是实现微波光透过墙壁(LSW)实验的理想候选者,因为它们分别显示出纳米TES和JES约100 GHz和2 GHz的前所未有的频率分辨率。

英文摘要:

The composition of dark matter is one of the puzzling topics in astrophysics. To address this issue, several experiments searching for the existence of axions have been designed, built and realized in the last twenty years. Among all the others, light shining through walls experiments promise to push the exclusion limits to lower energies. For this reason, effort is put for the development of single-photon detectors operating at frequencies $<100$ GHz. Here, we review recent advancements in superconducting single-photon detection. In particular, we present two sensors based on one-dimensional Josephson junctions with the capability to be in situ tuned by simple current bias: the nanoscale transition edge sensor (nano-TES) and the Josephson escape sensor (JES). These two sensors are the ideal candidates for the realization of microwave light shining through walls (LSW) experiments, since they show unprecedented frequency resolutions of about 100 GHz and 2 GHz for the nano-TES and JES, respectively.
