Abstract

The first synchrotron radiation beamline using a 4 m-long undulator at the 12 GeV storage ring PETRA delivers hard X-ray photons usable up to 300 keV. The photon intensity is measured on an absolute scale in the energy range between 16 and 60 keV and compared with calculated intensities. The experimental set-up described is also used to measure the horizontal and vertical emittance of the source.

摘要

在12 GeV储存环PETRA上，首个使用4米长波荡器的同步辐射光束线可产生最高300 keV的硬X射线光子。在16至60 keV的能量范围内，以绝对尺度测量光子强度，并与计算强度进行比较。所描述的实验装置还用于测量光源的水平和垂直发射度。
