我们正在研制一种具有高能量分辨率和位置灵敏度的X射线微量热计，它采用铱跃迁边缘传感器。具有新的像素型几何结构的Ir-TES具有十个小像素TES阵列。每个像素尺寸为80 μm ×200 μm。该器件在5.9 keV处具有26 eV（FWHM）的能量分辨率。此外，通过准直X射线微束沿沿着每个像素扫描Ir-TES膜，并在每个入射位置处测量信号脉冲。脉冲高度和上升时间图已经示出了对应于每个像素的脉冲集中的十个不同区域。这对于成像TES阵列可能是有用的。
We are developing an X-ray microcalorimeter with high energy resolution and position sensitivity by using an Iridium transition edge sensor. The Ir-TES with a new pixel-type geometry has ten small pixel TES array. Each pixel size is 80 μm ×200 μm . This device has shown a good energy resolution of 26 eV (FWHM) at 5.9 keV . Furthermore, the Ir-TES film was scanned along each pixel by a collimated X-ray microbeam and signal pulses were measured at each incident position. The pulse height and rise time map has shown ten different regions where pulses are concentrated which correspond to each pixel. This might be useful for an imaging TES array.
