使用过渡边缘传感器的微量热计X射线探测器的线性度和能量尺度取决于过渡曲线上工作点的稳定性。我们报告了微热量计X射线探测器中的一些能量标度漂移的来源以及它们被解决的方式。以前观测到的~gt；10 eV/h的漂移已经减少到1-2 eV/h。这一稳定性的提高导致在6小时的计数时间内观察到了⩽12 eV的X射线荧光线宽。
Microcalorimeter X-ray detectors using a transition edge sensor depend for their linearity and energy scale on the stability of the operating point on the transition curve. We report on some sources of energy scale drift in microcalorimeter X-ray detectors and the manner in which they have been addressed. Previously observed drifts of >10 eV∕h have been reduced to 1–2 eV∕h. This improved stability has resulted in the observation of X-ray fluorescence linewidths of ⩽12 eV over 6 h of counting time.
