Fast and thermal neutron flux measurements in test cavity outside HB-6 beam port in Plum Brook reactor using sulfur pellets and gold foils
Fluid inertia effects in foil bearings - mathematical analysis
Beam-foil technique of exciting electronic levels in atoms and ions applied to Al and Fe
Critical pinning current density for initiating flux flow in Pb-Bi type II superconducting foils, noting dependence on surface to volume ratio
Flux-flow resistivity and critical current density orientational dependence in Pb alloys type 2 superconducting foils under magnetic field, discussing Lorentz force
Electronic excitation of nitrogen beam passed through thin carbon target foil noting spectral lines, unidentified lines and decay times
High speed rotors are supported initially by flexible metal foil and then on an air film generated by a self-acting hydrodynamic effect. The flexibility of the bearing enables it to conform and deflect locally, wear is less severe, self-alignment and accommodation of thermal distortion is permitted.
