ZEUS-2 是第二代 (z) 红移和早期宇宙光谱仪，与其前身一样，是一款中等分辨率 (R~1000) 长缝中阶梯光栅光谱仪，针对探测来自遥远星系的微弱、宽线进行了优化。它旨在研究整个宇宙时间的恒星形成。 ZEUS-2 采用三个 TES 测辐射热计阵列（总共 555 个像素），可在多达 4 个亚毫米窗口中同时提供多光束光谱。 NIST Boulder 构建的阵列运行温度约为 100mK，并通过 SQUID 多路复用器和不列颠哥伦比亚大学的多通道电子设备进行读出。该仪器通过脉冲管冷却器和两级 ADR 进行冷却。各种滤波器配置使 ZEUS-2 能够访问从 200 到 850 微米的 7 个不同的大地窗口，从而能够同时绘制来自扩展源的线或同时检测来自 z = 1-2 星系的 158 微米 [CII] 线和 [NII] 122 或 205 微米线。 ZEUS-2 设计用于 CSO、APEX 以及可能的 JCMT。
ZEUS-2, the second generation (z)Redshift and Early Universe Spectrometer, like its predecessor is a moderate resolution (R~1000) long-slit, echelle grating spectrometer optimized for the detection of faint, broad lines from distant galaxies. It is designed for studying star-formation across cosmic time. ZEUS-2 employs three TES bolometer arrays (555 pixels total) to deliver simultaneous, multi-beam spectra in up to 4 submillimeter windows. The NIST Boulder-built arrays operate at ~100mK and are readout via SQUID multiplexers and the Multi-Channel Electronics from the University of British Columbia. The instrument is cooled via a pulse-tube cooler and two-stage ADR. Various filter configurations give ZEUS-2 access to 7 different telluric windows from 200 to 850 micron enabling the simultaneous mapping of lines from extended sources or the simultaneous detection of the 158 micron [CII] line and the [NII] 122 or 205 micron lines from z = 1-2 galaxies. ZEUS-2 is designed for use on the CSO, APEX and possibly JCMT.
