摘要:

当前一代毫米波长探测器受到复杂的低温读出电子器件所施加的缩放限制。为了规避这一点,必须研究本质上包含强复用的技术。一种可能的解决方案是动态电感检测器(KID)。为了评估这种新生技术的潜力,构建了针对2 mm大气窗口优化的原型仪器。它被称为Néel IRAM KIDS阵列(NIKA),最近在西班牙Pico Veleta的毫米射电天文学研究所(IRAM)30米望远镜进行了测试。测量结果导致了许多来源的成像,包括行星,类星体和星系。火星、射电星MWC349、类星体3C345和星系M87的图像被呈现出来。根据这些结果,光学NEP被计算为大约$1 \times 10^{-15}$ W $ / $ Hz $^{1/2}$。通过改进探测器材料和减少降低性能的杂散辐射,预计10倍的改进是可行的。

英文摘要:

Current generation millimeter wavelength detectors suffer from scaling limits imposed by complex cryogenic readout electronics. To circumvent this it is imperative to investigate technologies that intrinsically incorporate strong multiplexing. One possible solution is the kinetic inductance detector (KID). In order to assess the potential of this nascent technology, a prototype instrument optimized for the 2 mm atmospheric window was constructed. Known as the Néel IRAM KIDs Array (NIKA), it was recently tested at the Institute for Millimetric Radio Astronomy (IRAM) 30-meter telescope at Pico Veleta, Spain. The measurement resulted in the imaging of a number of sources, including planets, quasars, and galaxies. The images for Mars, radio star MWC349, quasar 3C345, and galaxy M87 are presented. From these results, the optical NEP was calculated to be around $1 \times 10^{-15}$ W$ / $Hz$^{1/2}$. A factor of 10 improvement is expected to be readily feasible by improvements in the detector materials and reduction of performance-degrading spurious radiation.
