凯克阵列是一种宇宙微波背景（CMB）偏振计，将于2010年底开始从南极进行观测。最初的部署将包括三个类似于BICEP 2的望远镜，安装在超紧凑的脉冲管冷却低温恒温器中。明年还将增加两个接收器。在这些诉讼中，我们报告的凯克低温恒温器的设计和性能。我们还报告了一些初步的结果天线耦合TES探测器的性能在脉冲管的存在下操作。我们发现，BICEP 2的液氦低温恒温器与脉冲管冷却的低温恒温器的更换的检测器的性能并没有受到严重影响。
The Keck Array is a cosmic microwave background (CMB) polarimeter that will begin observing from the South Pole in late 2010. The initial deployment will consist of three telescopes similar to BICEP2 housed in ultracompact, pulse tube cooled cryostats. Two more receivers will be added the following year. In these proceedings we report on the design and performance of the Keck cryostat. We also report some initial results on the performance of antenna-coupled TES detectors operating in the presence of a pulse tube. We find that the performance of the detectors is not seriously impacted by the replacement of BICEP2's liquid helium cryostat with a pulse tube cooled cryostat.
