Addressing the impact of non-linearity in superconductive bolometers to test cosmological inflation from space with a CMB polarimeter

关于这一建议的硬件方面，我们在加州大学伯克利分校的同事开发的TES测辐射热计的黑暗特性正在取得进展。我们已经能够测试类空间测辐射热计，并验证在临界温度，饱和功率和时间常数方面的要求。一个更先进的表征程序正在测试中，并已开始产生复阻抗的初步结果，可以补充其他方法，利用复用TES reading.We还开发了一个测试台，执行TES磁灵敏度测试，这是必要的，为未来的CMB实验，如LiteBIRD的磁屏蔽结构的设计提供信息。研究结果已在国际会议上发表，并作为会议论文集出版。模拟代码已被用于预测探测器非线性对模拟数据的影响。研究结果已在国际会议上提出，并发表在同行评审的期刊上。

Concerning the hardware side of this proposal, dark characterization of TES bolometers developed by our colleagues at UC Berkeley is progressing. We have been able to test space-like bolometers and verify the requirements in terms of critical temperature, saturation power and time-constant. A more advanced characterization procedure is being tested and has started producing preliminary results of complex impedance that can complement other methods that make use of multiplexing TES readout.We have also developed a test-bed to perform TES magnetic sensitivity tests that are necessary to inform the design of magnetic shielding structures for future CMB experiments like LiteBIRD. Results have been presented at international conferences and published as conference proceedings.The simulation code has been used to produced a forecast of the impact of detector non-linearity on simulated data. Results have been presented at international conferences and published on a peer reviewed journal.
