我们提出了5.9千电子伏的X射线在硅晶片利用频率多路复用动态电感探测器阵列的检测。读出电路由一个集成12位ADC的可编程数字电子器件组成，最大工作频率为100 MHz。我们采用集总元件几何结构，实现尽可能小的像素，以实现更好的位置分辨率。整个系统允许同时读出14个像素，带宽为300 kHz，但它很容易扩展到100个像素。更高的带宽探测，更少的像素，允许重建的光子吸收位置在基板高达数百微米。这项技术的发展可以在未来应用于大面积X射线成像。更好地了解高能光子和粒子探测对于LEKID在空间实施毫米天文学也至关重要，因为宇宙粒子造成的数据丢失可能是一个主要问题。
We present the detection of 5.9 keV X-rays in a silicon wafer utilising an array of frequency multiplexed Kinetic Inductance Detectors. The readout electronics consists of a programmable digital electronics with an integrated 12-bit ADC, operating with a maximum frequency of 100 MHz.We implement a lumped element geometry, realising pixels as small as possible in order to achieve better position resolution. The whole system allows the simultaneous readout of 14 pixels with a bandwidth of 300 kHz, but it is easily scalable up to 100 pixels. A higher bandwidth detection, with less pixels, allows the reconstruction of the photon absorption position in the substrate up to hundreds of microns.This technological development could be applied in the next future to large area X-Ray Imaging. A better understanding of high energy photon and particle detection is also crucial for the space implementation of LEKIDs for mm-astronomy, where data loss due to Cosmic particles could be a major issue.
