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-0138348LEE，ADRIANA毫米波降压接收器将为12米直径的Atacama Pathfinder Experiment（APEX）望远镜与Max Planck Institute for Max Planck for Niptitute for Max Planck Institute for Max Planck for for Bonn，德国波恩，德国，德国。 该接收器是150和217 GHz的观测值的300个元素侧验接收器。将使用spider-web设备进行螺旋耦合，并使用为1024个元素配置的Squid Ammeter读数，带有超导晶体管 - 边缘传感器（TES）。该接收器将用于通过毫米波长的热Sunyaev-Zel'Dovich（SZ）效应来发现和研究星系簇。 用光学和X射线测量记录的数据与该接收器承诺记录的数据相关时。揭示星系的形成历史，2。通过测量其状态方程来探测暗能的性质，3。测量宇宙学参数，包括质量能量密度和哈勃常数。 ***
