我们正在开发双极化多通道天线耦合跃迁边缘传感器(TES)测辐射热计,用于地面实验中的宇宙微波背景(CMB)偏振测量。阵列的每个像素将入射功率耦合到具有双极化宽带平面正弦天线的光刻微带电路中,该双极化宽带平面正弦天线的增益通过接触延伸的半球形透镜来增加。微带滤波器歧管将两个倍频程带宽划分为窄通道,然后终止于单独的TES测辐射热计。我们描述的设计方法和使用的制造方法,以及光学测试的结果,显示高的光吞吐量在适当的位置的频带,以及高的交叉偏振抑制。我们已经探讨了两种天线馈电方案,导致不同的质量波束,我们评论的相对优点。最后,我们量化了我们的多色像素阵列可能实现的映射速度比传统的单色像素的增加。
We are developing dual-polarized multi-channel antenna-coupled Transition Edge Sensor (TES) Bolometers for Cosmic Microwave Background (CMB) Polarimetry in terrestrial experiments. Each pixel of the array couples incident power into the lithographed microstrip circuits with a dual-polarized broadband planar sinuous antenna who's gain is increased with a contacting extended hemispherical lens. Microstrip filter manifolds partition the two-octave bandwidth into narrow channels before terminating at separate TES bolometers. We describe the design methodology and fabrication methods used, and also the results of optical tests that show high optical throughput in properly located bands, as well as high cross-polarization rejection. We have explored two antenna feeding schemes that result in different quality beams and we comment on the relative merits of each. Finally, we quantify the increases in mapping speed that an array of our multichroic pixels might realize over traditional monochromatic pixels.
