AST-0138348Lee, AdrianA millimeter wave bolometric receiver will be built for the 12-meter diameter Atacama Pathfinder Experiment (APEX) telescope in transition with Max Planck Institute for Radioastronomy (MPIfR) in Bonn, Germany. This receiver is a 300-element bolometric receiver for observations at 150 and 217 GHz. The bolometers will be horn-coupled, spider-web devices with superconducting transistor-edge sensors (TES) each using SQUID ammeter readout configured for 1024 elements. This receiver will be used to discover and study galaxy clusters via the thermal Sunyaev-Zel'dovich (SZ) effect at millimeter wavelengths. Data recorded with optical and x-ray measurements, when correlated with data recorded by this receiver promise to 1. reveal the formation history of galaxies, 2. Probe the nature of dark energy by measuring its equation of state, and 3. measure cosmological parameters including the mass energy density and the Hubble constant. ***

AST-0138348李，阿德里安毫米波测辐射热接收器将为12米直径的阿塔卡马探路者实验（APEX）望远镜建造，该望远镜将与德国波恩的马克斯普朗克射电天文学研究所（MPIfR）合作。 该接收器是一个300单元的测热接收器，用于在150和217 GHz进行观测。测辐射热计将是喇叭耦合的蜘蛛网设备，带有超导晶体管边缘传感器（TES），每个传感器都使用配置为1024个元件的SQUID安培计读数。该接收器将用于通过毫米波长的热Sunyaev-Zel'dovich（SZ）效应发现和研究星系团。 用光学和X射线测量记录的数据，当与该接收器记录的数据相关时，承诺为1。 揭示星系的形成历史，2.通过测量暗能量的状态方程来探索暗能量的本质;测量宇宙学参数，包括质量能量密度和哈勃常数。***
