同步辐射光源上的软X射线实验对于众多研究领域至关重要。然而，市场上针对这一能量范围的探测器往往无法在单一系统中同时提供所需的量子效率、信噪比、动态范围、速度和抗辐射能力。虽然混合探测器在硬X射线领域有效解决了这些挑战，特别是在高性能同步辐射应用中广泛使用的单光子计数像素探测器，但类似的解决方案对于低于2 keV的能量也备受期待。在本工作中，我们介绍了一种能够探测低至550 eV X射线能量的单光子计数混合像素探测器，利用了低增益雪崩二极管（LGAD）传感器的内部放大。该探测器在信噪比和探测量子效率方面进行了全面表征。我们通过在MAX IV第四代同步辐射光源上的Fe L3边（707 eV）的 Ptychography 成像展示了其性能，突显了系统的增强检测能力。这一进展为同步辐射中的软X射线应用设定了基准，为低光子能量下的成像和分析带来了显著进步。低增益雪崩二极管传感器的内部放大能够提升信噪比，改善低能X射线的探测。在本工作中，作者展示了一种能够探测低至550 eV X射线能量的单光子计数混合像素探测器，并测试了其在Fe L3边的Ptychography成像。
