论文摘要
低温微钙化器的阵列为X射线天体物理学提供了有前途的技术：成像光谱仪。一个具有至少数千像素的相机，每个像素具有能量可分辨的能力（$ e/δe\ urss {fwhm} $），在广泛的能量范围内（200 〜ev至10〜KeV或更高），将是研究能量天体物质物体和现象的革命工具。信号读数是一项至关重要的启示技术。多路复用的读数（其中多个像素的信号都合并为单个放大器通道，允许一公斤像素尺度的微晶格阵列满足轨道中功耗，质量，体积和冷却能力的严格要求。本章介绍了用于过渡边缘传感器微量标准器的三种不同的多路复用读取技术：时间划分多路复用，频域多路复用和微波炉多路复用。对于每种多路复用技术，我们介绍基本方法，讨论一些设计注意事项和参数，并显示最新的状态。本章以简短的讨论对未来的前景进行了讨论。
Arrays of low-temperature microcalorimeters provide a promising technology for X-ray astrophysics: the imaging spectrometer. A camera with at least several thousand pixels, each of which has an energy-resolving power ($E/ΔE\urss{FWHM}$) of a few thousand across a broad energy range (200~eV to 10~keV or higher), would be a revolutionary instrument for the study of energetic astrophysical objects and phenomena. Signal readout is a critical enabling technology. Multiplexed readout, in which signals from multiple pixels are combined into a single amplifier channel, allows a kilo pixel-scale microcalorimeter array to meet the stringent requirements for power consumption, mass, volume, and cooling capacity in orbit. This chapter describes three different multiplexed-readout technologies for transition-edge-sensor microcalorimeters: time-division multiplexing, frequency-domain multiplexing, and microwave-SQUID multiplexing. For each multiplexing technique, we present the basic method, discuss some design considerations and parameters, and show the state of the art. The chapter concludes with a brief discussion of future prospects.
