我们正在建造天线耦合的过渡边缘传感器测辐射热计阵列，以测量宇宙微波背景的极化。217千兆赫的原型像素先前已被表征，并显示出良好的性能(Myers等人)。在应用程序中。太棒了。让我们来吧。86：114103，[2005年])。我们的设计使用了双槽偶极子天线和集成的微带带定义滤波器。测试了包括片上测试结构在内的新器件，以提高我们对探测器性能的理解，并指导未来的发展。同时，还构建了基于原型像素设计的大型测辐射热计阵列。阵列像素是90 GHz、150 GHz和220 GHz的单频段像素的异质混合，现在采用双极化天线(IEEE Transans中的Chattopadhyay和Zmuidzinas)。天线问题。46：736，[1998])。给出了阵列像素的光学测试的初步结果。这些测辐射热计阵列将用于即将到来的CMB极化实验PolarBear。
We are building antenna-coupled Transition Edge Sensor bolometer arrays to measure the polarization of the cosmic microwave background. 217 GHz prototype pixels have previously been characterized and showed promising performance (Myers et al. in Appl. Phys. Lett. 86:114103, [2005]). Our design uses a double slot dipole antenna and an integrated microstrip band defining filter. New devices have been tested which include on-chip test structures to improve our understanding of detector performance and guide future development. In parallel with this, large arrays of bolometers based on the prototype pixel design have also been constructed. The array pixels are a heterogeneous mixture of single band pixels at 90 GHz, 150 GHz, and 220 GHz and now incorporate dual-polarization antennas (Chattopadhyay and Zmuidzinas in IEEE Trans. Antennas Propag. 46:736, [1998]). Preliminary results from optical testing of array pixels are presented. These bolometer arrays will be used in the upcoming CMB polarization experiment Polarbear.
