A 14×14×7‐in. Thin Plate Spark Chamber
(The American Institute of Physics, 1961-05)
A Lucite wall spark chamber with 0.012‐in. aluminum electrodes, active dimensions 14×14×7 in., has been constructed and tested both with cosmic rays and a particle beam. The gap efficiency is nearly 100% and the time ...
Ultimate sensitivity and practical performance of the tellurium photoconductive detector*
(Elsevier, 1961-03)
Calculations of the ultimate sensitivity and measurements of the practical performance have been made for the tellurium photoconductive detector. For the condition that detector sensitivity is limited by fluctuations of ...
Characteristics of Rotationally Stabilized Long Plasma Arcs in a Chamber
(The American Institute of Physics, 1969-08)
An analytical method is developed to determine the gas temperature distribution and the electric field strength‐arc length characteristics of a rotationally stabilized long plasma arc in a cylindrical chamber. The application ...
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 ...
EPR Spectrometer for Studying Crystals under High Hydrostatic Pressure
(The American Institute of Physics, 1964-07)
A spectrometer for studying the effect of hydrostatic pressure to 10 kbar on the electron paramagnetic resonance spectra of crystals is described. A two‐sample comparison method is used which greatly simplifies both the ...
Low‐Level Linear Microsecond Gate
(The American Institute of Physics, 1961-01)
A linear transmission gate for use in scintillation counter coincidence experiments is described. The gate is suitable for negative pulses of microsecond duration and is linear over a range of 0.01 to 5 v. The circuit is ...
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 ...
Linewidth Variations in ESR Spectra of o‐Dinitrobenzene Radicals
(The American Institute of Physics, 1967-05-15)
Elastic scattering of relativistic electrons by screened atomic nuclei
(Elsevier, 1963)
The effect of screening by atomic electrons on the scattering of relativistic electrons by heavy atoms has been computed numerically using different screening models. Exponential and Hartree potentials were used to simulate ...
Cutoff conditions for transverse circularly polarized electromagnetic waves in a finite temperature electro-magneto-ionic medium
(Elsevier, 1967-10)
The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The ...
