论文摘要
我们描述了气球传播Olimpo实验的角耦合的集体元件动感探测器阵列的机上性能。这些阵列的设计旨在与Olimpo：150、250、350和460 GHz的光谱谱带匹配，并且在Olimpo Poreload的平流层飞行过程中，它们在0.3 K和37.8 km的高度上进行操作，2018年夏季，在2018年夏季，我们在飞行中的第一小时都在驾驶中验证了大型探测器，并将其验证为远射的远射范围，远射范围的远射范围，远射范围的远射范围，远距离远射范围，远射范围的远射范围，远距离远射范围。插入式房间温度差异傅里叶转换光谱仪的插入到光链中。我们发现，检测器噪声当量的功率接近光子噪声限制，并且比在地面上测量的功率更低。此外，对于所有阵列的所有像素，击中阵列的主要宇宙射线造成的数据污染均小于3％，而大多数像素的数据污染物均小于1％。这些结果可以视为在代表性空间环境中儿童技术验证的第一步。
We describe the in-flight performance of the horn-coupled Lumped Element Kinetic Inductance Detector arrays of the balloon-borne OLIMPO experiment. These arrays have been designed to match the spectral bands of OLIMPO: 150, 250, 350, and 460 GHz, and they have been operated at 0.3 K and at an altitude of 37.8 km during the stratospheric flight of the OLIMPO payload, in Summer 2018. During the first hours of flight, we tuned the detectors and verified their large dynamics under the radiative background variations due to elevation increase of the telescope and to the insertion of the plug-in room-temperature differential Fourier transform spectrometer into the optical chain. We have found that the detector noise equivalent powers are close to be photon-noise limited and lower than those measured on the ground. Moreover, the data contamination due to primary cosmic rays hitting the arrays is less than 3% for all the pixels of all the arrays, and less than 1% for most of the pixels. These results can be considered the first step of KID technology validation in a representative space environment.
