TECHNICAL ACTIVITIES 1998 - NISTIR 6268
The Photon Physics Group (841.01) is primarily engaged in research in EUV optics, the development of EUV and x-ray microscopy, and the generation of coherent far ultraviolet radiation. It also operates an EUV optics characterization beamline at SURF II that provides custom calibrations for the soft x-ray optics community, the only such dedicated facility in the United States. Presently the Group is in the process of establishing an infrared microscope facility at SURF for use by the polymer, semiconductor, forensic, and medical communities.
The Far Ultraviolet Physics Group (841.02) is responsible for SURF II operations and for radiometric calibration services in the far ultraviolet and soft x-ray spectral regions (spanning the wavelength range 5 nm to 200 nm). The latter mission is pursued by operation of two dedicated calibration beamlines at SURF II: one primarily for custom calibrations of instrumentation,the other for calibration of photodiodes which are disseminated as transfer standards.
The Electron Physics Group (841.03) performs work on the frontiers of electron microscopy and laser manipulation of atoms. It has particular expertise in polarized electron technology, which led to the development of the SEMPA technique. It also has designed and constructed some of the world's most sensitive scanning tunneling microscopes, which can resolve vertical displacements of about a picometer. These instruments are presently used for studying a variety of surface phenomena, such as the microstructure of magnetic domains, thin-film growth, and the structure of complexes of adsorbed atoms. The Group has had a strong historical presence in the fields of electron-atom scattering and optical pumping of atomic beams, and has now applied its capabilities in these areas to attain a position of world leadership in the laser control of atomic adsorption on surfaces.
