论文摘要
用于天文学的墨西哥-UK亚毫米计摄像头（MUSCAT）是1.1 mm接收器，由1,500个集团元素动力学电感探测器（Lekids）组成，用于大毫米望远镜（LMT;volcán;VolcánSierranegra in Puebla in Puebla，Méxicococo）。马斯喀特利用LMT升级的50米主镜的最大视野，并且是第一次在大毫米望远镜上部署毫米/亚MM接收器的墨西哥-UK合作。使用简单的模拟器，我们通过将Muscat的测得的性能与LMT观察到的天空条件相结合来估计Muscat的预测映射速度。我们将其与先前计算的侧积模型映射速度进行比较，并发现当通过先前报道的经验因子缩放时，我们的映射速度非常一致。通过此模拟，我们表明，通过使用原理分析，可以有效地消除由于天空波动引起的信号污染。我们还概述了仪器设计，并解释了该设计如何升级Muscat，并在设施级Toltec接收器在线之后充当新型技术的天平演示测试床。
The Mexico-UK Submillimetre Camera for AsTronomy (MUSCAT) is a 1.1 mm receiver consisting of 1,500 lumped-element kinetic inductance detectors (LEKIDs) for the Large Millimeter Telescope (LMT; Volcán Sierra Negra in Puebla, México). MUSCAT utilises the maximum field of view of the LMT's upgraded 50-metre primary mirror and is the first México-UK collaboration to deploy a millimetre/sub-mm receiver on the Large Millimeter Telescope. Using a simplistic simulator, we estimate a predicted mapping speed for MUSCAT by combining the measured performance of MUSCAT with the observed sky conditions at the LMT. We compare this to a previously calculated bolometric-model mapping speed and find that our mapping speed is in good agreement when this is scaled by a previously reported empirical factor. Through this simulation we show that signal contamination due to sky fluctuations can be effectively removed through the use of principle component analysis. We also give an overview of the instrument design and explain how this design allows for MUSCAT to be upgraded and act as an on-sky demonstration testbed for novel technologies after the facility-class TolTEC receiver comes online.
