下一代线强度测绘（LIM）实验将需要极高通量的仪器，因此需要高像素数的焦平面。针对红移范围z=7-8的[CII]线研究，我们开发了工作在210-235 GHz范围、光谱分辨率达120的高光谱填充焦平面（FHYKID）。光谱滤波通过平面槽分裂环谐振器（SSRR）与集总元件动力学电感探测器（LEKID）耦合实现。该稳健方案凭借其简洁性实现了高量子效率，且具备可扩展性，即使采用当前读出电子系统也可扩展至天空上数万束光束。我们的FHYKID将成为NIKONA仪器的四个通道之一，该仪器目前正在寻求资金，计划安装在皮科贝雷塔的IRAM 30米望远镜上。其科学目标包括同时测绘本地（银河系及近邻星系）CO线和宇宙学[CII]线。
英文摘要
The next generation Line Intensity Mapping (LIM) experiments will require very high throughput instrumentation, and as a consequence high pixel counts focal planes. For the study of the [CII] line in the redshift range z=7-8, we develop a hyperspectral filled focal plane (FHYKID) operating in the range 210-235 GHz and with a spectral resolution reaching 120. The spectral filtering is achieved thanks to planar Slot Split Ring Resonators (SSRR) coupled to Lumped Element Kinetic Inductance Detectors (LEKID). This robust concept achieves, thanks to its simplicity, large quantum efficiency and is scalable, even with current readout electronics systems, to several tens of thousands beams on Sky. Our FHYKID will be one of the four channels of the NIKONA instrument, currently seeking funding and to be installed at the IRAM 30-meter telescope at Pico Veleta. Among the science goals, simultaneously mapping the local (galactic and nearby-galaxies) CO line and the cosmological [CII].
