Abstract
The Terahertz Intensity Mapper (TIM) is a balloon-borne far-infrared imaging spectrometer designed to characterize the star formation history of the universe. In its Antarctic science flight, TIM will map the redshifted 158um line of ionized carbon over the redshift range 0.5-1.7 (lookback times of 5-10 Gyr). TIM will spectroscopically detect ~100 galaxies, determine the star formation rate history over this time interval through line intensity mapping, and measure the stacked CII emission from galaxies in its well-studied target fields (GOODS-S, SPT Deep Field). TIM consists of a 2-meter telescope feeding two grating spectrometers that that cover 240-420um at R~250 across a 1.3deg field of view, detected with 7200 kinetic inductance detectors and sampled through a novel RF system-on-chip readout. TIM will serve as an important scientific instrument, accessing wavelengths that cannot easily be studied from the ground, and as a testbed for future FIR space technology.
太赫兹强度绘图仪(TIM)是一种气球载远红外成像光谱仪，旨在描述宇宙恒星形成历史。在其南极科学飞行中，TIM将在红移0.5-1.7(回望时间为5-10 Gyr)范围内绘制电离碳的158um红移线。TIM将对约100个星系进行光谱探测，通过线强度映射确定这段时间内恒星形成速率的历史，并在其研究充分的目标场(GOODS-S, SPT Deep Field)中测量星系的堆叠CII发射。TIM由一个2米的望远镜提供两个光栅光谱仪，在R~250下覆盖240-420um，横跨1.3°视场，通过7200个动态电感探测器进行检测，并通过新颖的射频片上系统读出器进行采样。TIM将作为一种重要的科学仪器，获取不容易从地面研究的波长，并作为未来FIR空间技术的试验台。
