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型测试芯片（16个检测器）的设计和制造，其中包括铝，尼伯群，钯等几个背景。这些检测器的频率和时域的低温恒温器在1.6 K的频率和时间域中进行了测试，并以时间相关的测量对两个探测器进行了同时的测量。同时，我们正在法国巴黎大学 - 萨克莱大学的低温恒温器中为100 MK的测量做准备。我们已经为该实验获得了测量实用程序，以及微波电路设计，允许在不使用多路复用读数的情况下进行这些测量。计划在100 mk的铝芯片上进行几项测试，这将与无金属芯片进行比较。我们预计这些测试将在接下来的6周内在巴黎萨克莱完成。
