A multifunctional ultrahigh vacuum (UHV) system has been set up at the nuclear resonance beamline ID18 of the European Synchrotron Radiation Facility (ESRF). Thin and ultrathin films, nanoislands and -wires, multilayers, and stoichiometric oxides can be prepared by molecular beam epitaxy and characterized by low-energy electron diffraction, Auger electron spectroscopy, and reflection high-energy electron diffraction. Upon characterization the sample is transferred under UHV conditions to the chamber for experiments with the synchrotron beam. Electronic and magnetic properties, vibrational dynamics, and diffusion phenomena can be investigated by several synchrotron radiation based techniques, such as nuclear forward scattering, nuclear inelastic and quasielastic scattering, synchrotron radiation based perturbed angular correlations, and nuclear and electronic reflectivity. In addition, two portable UHV chambers serve to transfer the sample to other beamlines profiting from the available experimental techniques at the ESRF.
在欧洲同步辐射装置（ESRF）的核共振光束线ID18上搭建了一个多功能超高真空（UHV）系统。可以通过分子束外延制备薄膜、超薄薄膜、纳米岛和纳米线、多层膜以及化学计量氧化物，并通过低能电子衍射、俄歇电子能谱和反射高能电子衍射对其进行表征。表征完成后，样品在超高真空条件下转移至用于同步加速器光束实验的腔室。可以通过几种基于同步辐射的技术研究电子和磁性特性、振动动力学以及扩散现象，例如核正向散射、核非弹性和准弹性散射、基于同步辐射的扰动角关联以及核反射率和电子反射率。此外，两个便携式超高真空腔室用于将样品转移至ESRF其他光束线，以便利用现有的实验技术。
