PROJECT OF THE OPTICAL DIAGRAM OF THE SYNCHROTRON RADIATION STATION ON THE RING SOURCE OF PHOTONS SKIF TO STUDY THE CHEMISTRY AND KINETICS OF FLAME COMBUSTION PROCESSES AND PYROLYSIS

The project of the station of synchrotron radiation of the second stage Plamya-2 for the Siberian ring photon source SKIF is based on the experience gained during the development of the station "Plamya" on the storage ring VÉPP-4 at the Siberian Center for Synchrotron Radiation (SR). The station is designed to study the processes of combustion and thermal decomposition of various organic compounds by the method of photoionization mass spectrometry using vacuum ultraviolet (VUV) synchrotron radiation. The use of selective photoionization by VUV radiation in the molecular beam method of sampling from the reaction zone in fl ames or pyrolyzers makes it possible to identify and quantify the concentrations of atoms, radicals, and other labile and short-lived compounds, which provides key information on chemical transformations under conditions of high-speed combustion and thermal decomposition. The paper considers the possibility of using various SR generators available on the SKIF storage ring, as well as the optical scheme of the station and the conceptual design of its front-end. The experimental results of measuring photon fl uxes for the Plamya station and the calculated photon fl uxes on the sample for the Plamya-2 station are also presented.
