我们首先展示了X射线TES和直接耦合微波SQUID复用器（D-coup）之间的合作。MW-Mux），其中SQUID直接耦合到谐振器。使用D-coup。MW-Mux，我们成功地检测到来自单像素TES的X射线脉冲，并评估了5.9 keV下11.8 eV FWHM的能量分辨率。我们发现这种初步的能量分辨率归因于目前TES的非最佳偏置点，这可以通过未来的读出噪声的降低来改善。
We have first demonstrated the cooperation between an X-ray TES and a directly coupled microwave SQUID multiplexer (D-coup. MW-Mux) in which SQUIDs are directly coupled to resonators. Using D-coup. MW-Mux, we successfully detected the X-ray pulses from a single-pixel TES and evaluated the energy resolution of 11.8 eV FWHM at 5.9 keV. We found this preliminary energy resolution is attributed to non-optimum bias point of the present TES, which can be improved by the future reduction of readout noise.
