Abstract

The European X-ray Free Electron Laser (XFEL.EU) is currently being commissioned in Schenefeld, Germany. From 2017 onwards it will provide spatially coherent X-rays of energies between 0.25 keV and 25keV with a unique timing structure. One of the detectors foreseen at XFEL.EU for the soft X-ray regime (energies below 6keV) is a quasi column-parallel readout FastCCD developed by Lawrence Berkeley National Lab (LBNL) specifically for the XFEL.EU requirements. Its sensor has 1920×960 pixels of 30μm ×30μm size with a beam hole in the middle of the sensor. The camera can be operated in full frame and frame store mode. With the FastCCD a frame rate of up to 120 fps can be achieved, but at XFEL.EU the camera settings are optimized for the 10Hz XFEL bunch-mode. The detector has been delivered to XFEL.EU. Results of the performance tests and calibration done using the XFEL.EU detector calibration infrastructure are presented quantifying noise level, gain and energy resolution.

用于欧洲XFEL的LBNL快速ccd的性能

欧洲x射线自由电子激光器(XFEL.EU)目前正在德国Schenefeld进行调试。从2017年起，它将以独特的定时结构提供能量在0.25 keV到25keV之间的空间相干x射线。XFEL预见的探测器之一。EU用于软x射线(能量低于6keV)是由劳伦斯伯克利国家实验室(LBNL)专门为XFEL开发的准柱平行读出快速ccd。欧盟的要求。该传感器的像素尺寸为1920×960，尺寸为30μm ×30μm，传感器中间有一个光束孔。该相机可在全画幅和帧存储模式下操作。使用FastCCD可以实现高达120 fps的帧速率，但在XFEL下。相机设置针对10Hz XFEL束模式进行了优化。探测器已经交付给xfl . eu。使用XFEL完成的性能测试和校准结果。给出了EU探测器的噪声级、增益和能量分辨率的定标基础结构。
