Development of radiation-resistant superconducting detector arrays for satellite missions in the millimetre waveband

我们已经完成了几个小型测试芯片（16个探测器）的设计和制造，包括铝，铌，钯等几种支持。这些探测器在冈山大学的低温恒温器中在1.6 K下进行了频率和时域测试，同时对两个探测器进行了时间相关的测量。与此同时，我们正准备在法国巴黎萨克雷大学的低温恒温器中进行100 mK的测量。我们已经为这个实验获得了测量工具，以及微波电路设计，允许这些测量而不使用多路复用读出。计划在100 mK下对铝芯片进行几次测试，并将其与无金属芯片进行比较。我们预计这些测试将在未来6周内在巴黎萨克雷完成。

We have completed the design and fabrication of several small test chips (16 detectors) with several backings including aluminium, niobium, palladium, etc. These detectors were tested at 1.6 K in the cryostat at Okayama University in both the frequency and the time domain, with time-dependent measurements taken on two detectors simultaneously. In the meantime, we are preparing for measurements at 100 mK in a cryostat at the University of Paris-Saclay in France. We have acquired measurement utilities for this experiment, as well as microwave circuit design allowing for these measurements without the use of multiplexing readout. Several tests are planned for the Aluminium chip at 100 mK which will be compared with those of the metal-free chip. We anticipate that these tests will be completed in the next 6 weeks at Paris Saclay.
