The Introduction of Photochemistry Station in HESYRL

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.
