HOLOGRAPHY WITH SPATIALLY NONCOHERENT LIGHT
(The American Institute of Physics, 1965-11-01)
Enhancement of Plasma Density in an Arc Discharge
(The American Institute of Physics, 1965-11)
The amplification or generation of coherent signals by electron‐beam—plasma interactions requires the creation of a high‐density stable plasma. A plasma density of approximately 1015 particles∕cm3 is required to produce a ...
Motion of a Sphere in a Rotating Fluid at Small Reynolds Numbers
(The American Institute of Physics, 1965-04)
The slow steady rise of a solid sphere along the axis of a uniformly rotating viscous liquid is studied when the Reynolds number, based on the translational velocity along the axis of rotation, is less than unity. The ...
Method of Producing a Fast Current Rise from Energy Storage Capacitors
(The American Institute of Physics, 1965-07)
A rate of current rise of the order of 1013 A sec−1 can be produced by inexpensive capacitors used in conjunction with a special, low inductance fuse and spark gap. The capacitors are discharged through the fuse until the ...
Slow Viscous Shear Flow past a Plate in a Channel
(The American Institute of Physics, 1965-11)
Flow past a plate midway between two walls is studied analytically using the Stokes approximation. An exact solution is found for the semi‐infinite plate using the Wiener‐Hopf technique. For the finite plate an approximate ...
Noise Transformation and Cyclotron Waves in Crossed Fields
(The American Institute of Physics, 1965-01)
A transmission‐line analog is developed for crossed‐field space‐charge flows from the simultaneous solution of Maxwell's equations, the Lorentz force equation, and the continuity equation. A thin one‐dimensional injected ...
RESOLUTION‐RETRIEVING SOURCE‐EFFECT COMPENSATION IN HOLOGRAPHY WITH EXTENDED SOURCES
(The American Institute of Physics, 1965-09-15)
Time‐Dependent One‐Speed Albedo Problem for a Semi‐Infinite Medium
(The American Institute of Physics, 1965-07)
A Laplace transformation technique is used to determine the neutron distribution in a semi‐infinite medium which has been irradiated by a neutron pulse. The result is given in terms of known solutions of Milne's problem ...
Sphere Drag in Flows of Almost‐Free Molecules
(The American Institute of Physics, 1965-05)
A kinetic theory of sphere drag in the transition flows, based on the Boltzmann equation for the Maxwellian molecules, is presented. The exact binary collision integral, in the first order Knudsen iteration, is expanded ...
Hydrodynamic Analysis of Noise in a Finite‐Temperature Electron Beam
(The American Institute of Physics, 1965-08)
On the basis of a small‐signal, one‐dimensional analysis, a set of basic macroscopic differential equations, governing the fluctuations in quantities such as the electron‐beam temperature, the mean velocity, and the current ...
