    Notes: A description is given of the prototype polarized neutron reflectometer installed at the intense pulsed neutron source. This instrument is designed for determining the magnetic depth profiles near the surfaces of ferromagnets and superconductors, by measuring the spin-dependent reflectivities of a well-collimated (0.01°) beam of cold neutrons from surfaces of a few cm2. Magnetic profiles can be determined with the spatial resolution of 40 A(ring), over thicknesses up to 5000 A(ring). Variations of the magnetic flux of the order of 10−5 G cm2 can be detected.

    Electronically focused time-of-flight powder diffractometers at the intense pulsed neutron source (1989)

    Notes: Two time-of-flight powder diffractometers have operated at the Intense Pulsed Neutron Source (IPNS) since August 1981. These instruments use dedicated microcomputers to focus time-of-flight events so that data from different detectors can be summed into a single histogram. Thus, large multidetector arrays can be employed at any scattering angle from 12 to 157°. This design permits data to be collected over a uniquely wide range of d spacings while maintaining high resolution and count rates. The performance of the two instruments is evaluated by analyzing data from a standard Al2O3 sample by the Rietveld method. These instruments provide the capability for moderate- to high-resolution measurements with the duration of a typical run being a few hours.

    Low power laser Rayleigh probe for flow mixing studies (1987)
    Springer
    Experiments in fluids 5 (1987), S. 230-234

    Notes: Abstract A laser Rayleigh correlation probe was constructed, which allows the application of low cost, low power (milliwatt) laser sources. It was tested for basic mixing studies in isothermal binary gas flows. Here, it can be used for the time and space resolved measurement of the concentration mean value and of all important statistical quantities, which give information on the distribution around the concentration mean value (rms, skewness, kurtosis) and on the relation of adjecent fluctuations in time or space (autocorrelation function, power spectral density).

    Notes: Zusammenfassung Es wird über den Mechanismus der Blutdrucksenkung nach d-Tubocurarin berichtet, und die Lokalisation des Angriffspunktes näher untersucht. Pharmakologische Beeinflussung des adrenergischen, cholinergischen und histaminergischen Systems blieb ohne Erfolg. Es wird ein direkter „muskulotroper“ Angriffspunkt an der glatten Muskulatur der Gefäße des Magen-Darm-Traktes diskutiert.
