    Notes: The performance of a scanning photoelectron microscope at the MAX I storage ring in Lund is presented. The microscope utilizes undulator radiation in the energy range 15–150 eV and is comprised of a plane-grating monochromator with a Kirkpatrick–Baez objective and a gracing incidence ellipsoidal focusing mirror. The instrument with its high photon flux, 109–1010 photons/s, and narrow bandwidth, better than 0.2 eV, is excellently suited for high-resolution core-level spectroscopy and imaging of samples with lateral inhomogeneties in the micrometer range. © 1995 American Institute of Physics.

    Notes: The design of a photoemission microprobe beamline at the MAX laboratory is presented. The beamline will utilize the radiation from a 26 period undulator on the 550-MeV MAX storage ring. The beamline will be capable of providing about 1010 photons/s of monochromatized radiation (bandwidth better than 0.25 eV) in the energy range of 20 to 150 eV focused into a submicrometer focal spot. It will be used for scanning photoemission experiments with a lateral resolution better than 1 μm. The optical system is comprised of a plane-grating monochromator with a Kirkpatrick–Baez objective and a specially designed ellipsoidal focusing mirror.

    Notes: Thin films of superconducting BiCaSrCuO have been grown by molecular beam epitaxy depositions of Bi, Cu, and CaF2/SrF2 on MgO and SrTiO3 followed by a high-temperature oxygen anneal. The films showed a fairly wide transition of 20 K at a Tc of 80 K. Residual amounts of fluorine, detected with secondary-ion mass spectrometry, are believed to cause the broad superconducting transition. X-ray diffraction analysis of the superconducting films revealed strongly c-axis oriented films consisting of Bi2CaSr2Cu2O8 and Bi2Sr2Cu1O6 phase. Surface structure studies, with scanning electron microscopy and scanning tunneling microscopy, show oriented 1 μm sized very smooth flat grains of superconducting phase in the plane of the film with islands of CuOx scattered on top of these.

    Description / Table of Contents: Zusammenfassung Durch Vergleichsuntersuchungen von Entnahmetechniken wurde gezeigt, daß Proben zur Vermeidung von Kontamination mit Anaerobierflora vorzugsweise durch Aspiration gewonnen werden sollten. Anaerobe Transportsysteme werden empfohlen, obwohl einige Anaerobierstämme Luftexposition erstaunlich gut vertragen. Ein von atmosphärischer Luft befreites Röhrchen oder Gefäß ist die Methode der Wahl für den Transport von flüssigen Untersuchungsproben für die anaerobe Kultur.
    Notes: Summary By comparative studies of sampling methods it was shown that specimens should be obtained preferably by aspiration in order to avoid contamination by anaerobic flora. Anaerobic transport systems are recommended, though some anaerobic strains tolerate exposure to air surprisingly well. A gassed-out tube or vial is the method of choice for transporting fluid specimens for anaerobic culture.
