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.

我们已经完成了几个小的测试芯片（16个探测器）的设计和制造与几个背衬，包括铝，铌，钯等这些探测器进行了测试，在1.6 K的低温恒温器在冈山大学在频率和时间域，与时间相关的测量上采取两个探测器同时进行。与此同时，我们正在法国巴黎萨克雷大学的低温恒温器中准备100 mK的测量。我们已经获得了该实验的测量实用程序，以及允许在不使用多路复用读出的情况下进行这些测量的微波电路设计。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。
