BICEP2/Keck 和 SPIDER 是宇宙微波背景 (CMB) 偏振计,其目标是由膨胀引起的原初引力波引起的 B 模式偏振。他们将使用极化敏感天线耦合 TES 测辐射热计平面阵列,工作频率在 90 GHz 至 220 GHz 之间。在 150 GHz 时,每个阵列由 64 个偏振计组成,其中四个阵列组装在一起形成焦平面,总共有 256 个双偏振元件(512 个 TES 传感器)。探测器阵列与 NIST 开发的时域 SQUID 多路复用器集成,并使用不列颠哥伦比亚大学开发的多通道电子器件 (MCE) 进行读取。随着我们在提高整个阵列的探测器参数均匀性和制造良率方面取得进展,我们的主要工作集中在提高探测器阵列的光学和噪声性能,以生产达到目标灵敏度的科学级焦平面。我们报告了为优化此类性能而实施的探测器设计变化以及遵循焦平面阵列特征。 BICEP2 于 2009 年 12 月在南极部署了第一个 150 GHz 科学级焦平面。
BICEP2/Keck and SPIDER are cosmic microwave background (CMB) polarimeters targeting the B-mode polarization induced by primordial gravitational waves from inflation. They will be using planar arrays of polarization sensitive antenna-coupled TES bolometers, operating at frequencies between 90 GHz and 220 GHz. At 150 GHz each array consists of 64 polarimeters and four of these arrays are assembled together to make a focal plane, for a total of 256 dual-polarization elements (512 TES sensors). The detector arrays are integrated with a time-domain SQUID multiplexer developed at NIST and read out using the multi-channel electronics (MCE) developed at the University of British Columbia. Following our progress in improving detector parameters uniformity across the arrays and fabrication yield, our main effort has focused on improving detector arrays optical and noise performances, in order to produce science grade focal planes achieving target sensitivities. We report on changes in detector design implemented to optimize such performances and following focal plane arrays characterization. BICEP2 has deployed a first 150 GHz science grade focal plane to the South Pole in December 2009.
