摘要
建设在中国科技大学内的国家专用同步辐射光源已通过国家验收并投入使用。光化学实验站是首批建成的实验装置之一,它由同步辐射真空紫外单色仪、超声分子束、光电离室以及控制与数据采集系统组成。可进行分子、自由基和小分子微团簇的光电离研究,获得关于能态、电离势、离解能、质子亲和能、反应通道等方面的信息.本文着重介绍装置及其性能,并给出初步实验结果.
The national dedicated synchrotron radiation source located in USTC has been checked and accepted by the government and put into operation. The photochemistry station is one of the first five stations completed. It consists of a VUV tunable monochromator, a supersonic molecular beam source, a photoionization chamber and a control and data acquision system. In the station, photoionization of molecules, radicals and molecular clusters can be studied and their energy levels, ionization potentials, dissociation energies, preton affinities and reaction chanals can be obtained. In this paper we described the experimental set up of the station and its performance in detail and outlined the preliminary experimental results.
