自2012年初以来,在智利北方阿塔卡马沙漠5,200米的位置,一直在观测北极熊宇宙微波背景(CMB)偏振实验。北极熊的测量将通过大尺度结构表征由于引力透镜引起的预期CMB偏振,寻找可能的B-暴胀引力波的模式偏振特征。polarbear的250 mK焦平面探测器阵列由1,274个偏振敏感天线耦合测辐射热计组成,每一个都具有相关联的光刻带限定滤波器和接触电介质小透镜,这是当前CMB实验中唯一的结构。本文介绍了该仪器的现状、焦平面和测量结果的分析。
Thepolarbearcosmic microwave background (CMB) polarization experiment has been observing since early 2012 from its 5,200 m site in the Atacama Desert in Northern Chile.polarbear’s measurements will characterize the expected CMB polarization due to gravitational lensing by large scale structure, and search for the possible B-mode polarization signature of inflationary gravitational waves.polarbear’s 250 mK focal plane detector array consists of 1,274 polarization-sensitive antenna-coupled bolometers, each with an associated lithographed band-defining filter and contacting dielectric lenslet, an architecture unique in current CMB experiments. The status of thepolarbearinstrument, its focal plane, and the analysis of its measurements are presented.
