The Molecular Beams apparatus operates on terminal 3. It uses a continuous molecular beam of a sample in argon with stagnation pressure up to 7 bar. The machine may handle gas, liquid, or solid samples. The molecular beam travels through an orifice to the interaction region where it is ionized by the synchrotron radiation. The nozzle orifices are 100/50μm.
Studies of interest include the photoionization dynamics of gas-phase DNA bases, microsolvation of DNA bases and small water clusters, the formation mechanisms of polycyclic aromatic hydrocarbons (PAHs) with indene and naphthalene cores in hydrocarbon-based combustion processes, the unimolecular decomposition of molecules relevant to biofuel combustion, spectroscopy, astrophysics and cosmochemistry.
