论文摘要
我们描述了用于放牧发病率快速原子衍射（GIFAD）实验的UHV设置。总体几何形状只是面对成像检测器的KEV原子的来源。因此，它与Rheed实验的几何形状非常相似，反射高能电子衍射用于监测表面的生长。描述了几种自定义仪器开发，使Gifad操作有效而直接。仔细分析了与准确测量较小的散射角和相关校准相关的困难。
We describe a UHV setup for grazing incidence fast atom diffraction (GIFAD) experiments. The overall geometry is simply a source of keV atoms facing an imaging detector. Therefore, It is very similar to the geometry of RHEED experiments, reflection high energy electron diffraction used to monitor growth at surfaces. Several custom instrumental developments are described making GIFAD operation efficient and straightforward. The difficulties associated with accurately measuring the small scattering angle and the related calibration are carefully analyzed.
