我们开发了用于 X 射线天文学的金属磁量热仪原型阵列。每个像素均由与金铒顺磁薄膜温度计保持良好热接触的全金 X 射线吸收器组成，温度范围为 30–100 mK。顺磁响应耦合到 SQUID 放大器。我们对阵列中的像素进行了表征，并观察了磁化强度和热容量的预期温度依赖性。我们已经展示了 6 keV 下 1.7 $$pm $$± 0.1 eV 的半高全宽能量分辨率，并且还使用时分复用读取了这些设备。
We have developed prototype arrays of metallic magnetic calorimeters for applications in X-ray astronomy. Each pixel consists of an all-gold X-ray absorber in good thermal contact to a gold-erbium paramagnetic thin film thermometer that is operated in the temperature range of 30–100 mK. The para-magnetic response is coupled to a SQUID amplifier. We have characterized pixels in an array and observed the expected temperature dependence of the magnetization and heat capacity. We have demonstrated a full width at half maximum energy resolution of 1.7 $$pm $$± 0.1 eV at 6 keV and have also read out these devices using time-division multiplexing.
