A new FReLoN (Fast-Readout Low-Noise) high-frame-rate detector adopted for the fast continuous collection of X-ray absorption spectra is presented. The detector is installed on the energy-dispersive X-ray absorption beamline ID24 at the ESRF and is capable of full time-resolved EXAFS spectra collection with over 4 kHz repetition rate and 0.2 ms exposure time. An example of the in situ kinetic study of the high-temperature oxidation of metallic iron is presented.
本文介绍了一种新的FReLoN（快速读出低噪声）高帧率探测器，用于快速连续采集X射线吸收光谱。该探测器安装在欧洲同步辐射装置（ESRF）的能量色散X射线吸收光束线ID24上，能够以超过4 kHz的重复率和0.2 ms的曝光时间进行全时间分辨扩展X射线吸收精细结构（EXAFS）光谱采集。文中给出了金属铁高温氧化原位动力学研究的一个示例。
