We report here on the coupling of a gas reactor with a VUV beamline at the SOLEILsynchrotron radiation facility. The reactor may be irradiated window-less with gaspressure up to the atmosphere. The photochemistry is monitored by a mass spectrometer gasanalyzer. This set up, termed APSIS for Atmospheric Photochemistry SImulated bySynchrotron, has been used to simulate the atmosphere of Titan and to study the formationof the photochemical smog and the formation of tholins.
