Ultralinear Cathode Follower
(The American Institute of Physics, 1960-09)
The design of a modified cathode follower circuit which possesses an extremely linear response and a voltage gain of essentially unity is presented. Analysis of the circuit shows that, in principle, the harmonic distortion ...
Experimental Investigation of a High‐Energy Density, High‐Pressure Arc Plasma
(The American Institute of Physics, 1960-02)
The underwater spark is utilized to study the fundamental parameters of a plasma at 30 000°K and 10 000 atmos pressure. The 25‐kv spark is obtained by underwater discharge of capacitors having a stored energy of 1800 joules, ...
Electron Diffraction Study of Monomethyl‐ and Dimethylphosphine
(The American Institute of Physics, 1960-03)
The structural parameters of gaseous monomethyl‐ and dimethylphosphine were determined by the sector‐microphotometer method of electron diffraction. Center of gravity bond distances and standard errors for the two molecules ...
A Simple Method for Improving the Accuracy of Cross‐Spectral Density Measurements
(The American Institute of Physics, 1960-09)
Electron Diffraction Study of the Structure of Trimethylphosphine
(The American Institute of Physics, 1960-02)
The structural parameters of gaseous trimethylphosphine, including standard errors, were found to be as follows: center of gravity bond distances were rCP=1.8465±0.003 A, and rCH=1.091±0.006 A; angles were <C☒P☒C=98.6±0.3°, ...
Effect of Nuclear Polarization on the Behavior of Solid State Masers
(The American Institute of Physics, 1960-05)
Transport of Noise at Microwave Frequencies through a Space‐Charge‐Limited Diode
(The American Institute of Physics, 1960-06)
Several analyses of the transport of cathode shot noise through a space‐charge‐limited diode at microwave frequencies have been published to date. Each of these analyses has been beset by inconsistencies arising from ...
Quantum Mechanical (Phase Shift) Analysis of Differential Elastic Scattering of Molecular Beams
(The American Institute of Physics, 1960-09)
For a spherically symmetrical intermolecular potential V(r)=ϵf(r/σ) the quantum calculation of the elastic scattering cross section dσ(Θ)/dΩ in the c.m. system is carried out as follows. For a given relative velocity (or ...
Improved Slotted Disk Type Velocity Selector for Molecular Beams
(The American Institute of Physics, 1960-08)
A slotted disk type mechanical velocity selector, 10 cm long and 16 cm in diameter, consisting of six disks has been constructed and tested. The velocity resolution corresponding to the half‐intensity width is 0.047; no ...
Differential‐Operator Approximations to the Linear Boltzmann Equation
(The American Institute of Physics, 1960-09)
A measure of deviation from equilibrium of an ensemble of particles is proposed, which is physically appropriate and of especially simple form when expressed in terms of the expansion coefficients of the ensemble distribution ...
