摘要:

我们已经制作了多层读出布线过渡边缘传感器(TES),这使我们能够实现大的有效面积和高能量分辨率的未来X射线天体物理任务,如DIOS。通过在Al超导信号线和返回线之间添加SiO2绝缘层,可以减少偏置引线的自感/互感和自磁场。我们在多层布线上制作了4 × 4和20 × 20 TES阵列,并测试了它们的性能。在低温条件下,TES阵列中的几个像素在约300 mK处显示出尖锐的超导转变。我们还成功地检测到来自4x 4 TES的X射线信号,与之前20 x20 TES的结果相反。我们进一步研究了4x 4 TES和20 x20 TES之间差异的原因,并提出了未来改进多层TES阵列制造的计划。

英文摘要:

We have fabricated multilayer readout wiring Transition Edge Sensors (TES), which enable us to realize both large effective area and high-energy resolution for future X-ray astrophysical missions, such as DIOS. By sandwiching a SiO2 insulation layer between Al superconducting signal and return lines, self/mutual inductances and self fielding of bias leads are expected to be reduced. We fabricated 4x4 and 20x20 TES array on the multilayer wiring and tested their performance. Under the low temperature condition, several pixels in the TES array showed sharp superconducting transitions at around ~300 mK. We also succeeded in detecting X-ray signals from the 4x4 TES, contrary to the previous results of 20x20 TES. We further investigated the reasons for the differences between the 4x4 TES and the 20x20 TES, and present future plans for improving the multilayer TES array fabrication.
