摘要:

微波动力学电感探测器(MKID)已被证明是一种强大的低温探测器技术,因为它们具有灵敏度,并且可以轻松地将它们多路复用到大型阵列中。MKID是基于光刻微谐振器中的光子可变超导电感的能量传感器,并且能够用作跨越电磁波谱的光子探测器以及粒子探测器。在这里,我们描述了第一次成功的努力,创造一个光子计数,能量分辨紫外线,光学和近红外MKID焦平面阵列。这些新的光学集总元件(OLE)MKID阵列与电荷耦合器件(CCD)等半导体探测器相比具有显着的优势。它们可以计数单个光子,基本上没有错误计数,并以良好的量子效率确定每个光子的能量和到达时间。它们的物理像素大小和最大计数率与大型望远镜非常匹配。这些能力使强大的新天体物理仪器能够从地面和空间使用。MKID最终可以取代大多数天文仪器的半导体探测器,并将用于其他学科,如量子光学和生物成像。

英文摘要:

Microwave Kinetic Inductance Detectors, or MKIDs, have proven to be a powerful cryogenic detector technology due to their sensitivity and the ease with which they can be multiplexed into large arrays. A MKID is an energy sensor based on a photon-variable superconducting inductance in a lithographed microresonator, and is capable of functioning as a photon detector across the electromagnetic spectrum as well as a particle detector. Here we describe the first successful effort to create a photon-counting, energy-resolving ultraviolet, optical, and near infrared MKID focal plane array. These new Optical Lumped Element (OLE) MKID arrays have significant advantages over semiconductor detectors like charge coupled devices (CCDs). They can count individual photons with essentially no false counts and determine the energy and arrival time of every photon with good quantum efficiency. Their physical pixel size and maximum count rate is well matched with large telescopes. These capabilities enable powerful new astrophysical instruments usable from the ground and space. MKIDs could eventually supplant semiconductor detectors for most astronomical instrumentation, and will be useful for other disciplines such as quantum optics and biological imaging.
