我们建造了一台新的长缝光栅光谱仪(ZEUS-2)，用于在亚毫米波长(200-650μm)范围内进行观测。宙斯2号是为观测宇宙早期星系的红移远红外光谱线而优化的。该光谱仪采用了三个过渡边缘传感测辐射热计阵列，允许在几个大地窗口中同时观测多条线。在这里，我们将讨论宙斯-2的光学、机械和热要求，以及它们随后的设计和性能。整个仪器使用脉冲管制冷机和绝热退磁制冷机进行冷却。这种无制冷剂的方法能够远程控制冷却系统，并允许将宙斯-2部署到进入受限的望远镜地点。紧凑轻便的设计也符合几个亚毫米望远镜的尺寸和重量限制，使宙斯2号可以部署在各种地点。2012年5月，宙斯2号在莫纳克亚的CSO完成了一次成功的工程运行，我们计划将我们的科学级阵列系统部署在智利的APEX望远镜上，以便于2012年秋天进行科学运行。
We have built a new long-slit grating spectrometer (ZEUS-2) for observations in the submillimeter wavelength regime (200-650 μm). ZEUS-2 is optimized for observations of redshifted far-infrared spectral lines from galaxies in the early Universe. The spectrometer employs three transition-edge sensed bolometer arrays, allowing for simultaneous observations of multiple lines in several telluric windows. Here we will discuss the optical, mechanical, and thermal requirements of ZEUS-2 and their subsequent design and performance. The entire instrument is cooled using a pulse tube cryocooler and an adiabatic demagnetization refrigerator. The cryogen-free approach enables remote control of the cooling system and allows for deployment of ZEUS-2 to telescope sites where access is limited. The compact and lightweight design is also within the size and weight constraints of several submm telescopes, making ZEUS-2 deployable at a variety of sites. ZEUS-2 completed a successful engineering run at the CSO on Mauna Kea in May 2012, and we plan to have our science-grade array system deployed on the APEX telescope in Chile for a science run in the fall of 2012.
