中文摘要
关于该提案的硬件方面,我们在加州大学伯克利分校的同事开发的TES辐射热计的暗表征正在进行中。我们已经能够测试类似太空的辐射热计,并验证临界温度、饱和功率和时间常数方面的要求。一种更先进的表征程序正在测试中,并已开始产生复杂阻抗的初步结果,可以补充使用多路复用TES读出的其他方法。我们还开发了一个试验台,用于进行TES磁灵敏度测试,这对于未来的宇宙微波背景实验(如LiteBIRD)的磁屏蔽结构设计是必要的。研究结果已在国际会议上发表,并作为会议论文集出版。利用仿真代码对探测器非线性对仿真数据的影响进行了预测。研究结果已在国际会议上发表,并发表在同行评议的期刊上。
英文摘要
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.
