Superconducting Thin-Film Transformers at Microwave Frequencies

June 1, 1999
Author(s)
A. H. Miklich, J. X. Przybysz, T. J. Smith, Samuel Benz, Todd E. Harvey
… superconducting transformers at frequencies up to 20 GHz. Transformers with turns ratios of 2,3, and 7 were fabricated out of Nb and tested in a liquid-He Dewar. …

Viscoelasticity of Xenon Near the Critical Point

February 1, 1999
Author(s)
Robert F. Berg, Michael R. Moldover, G A. Zimmerli
Using a novel, overdamped, oscillator flown aboard the Space Shuttle, we measured the viscosity of xenon near the liquid-vapor critical point in the frequency range 2 Hz [less than or equal to} f {less than or equal to} 12 Hz. The measured viscosity
