The apparatus is designed to adsorb precise and reproducible doses to a defined area on metal oxide samples, which is required in Temperature Programmed Desorption and other surface chemistry experiments. The design and the construction of the apparatus is described. The properties of the molecular beam are experimentally confirmed. The beam profile has a core diameter of 3.5 mm and a standard core pressure of 4 x 10-8 mbar, while the background pressure is 4 orders of magnitude lower. Contents Flow of Gases Effusive Molecular Beam Sources Molecular Beam Target Groups Researchers and students in the fields of surface physics and surface chemistry The Author Daniel Halwidl finished his master thesis under the supervision of Prof. Dr. Ulrike Diebold at the Institute of Applied Physics at the TU Wien. Currently, he is researching the fundamentals of the surface chemistry of perovskite-based solid oxide fuel cell materials to obtain his PhD. ER -
