Abstract : Research is directed towards explaining quantitatively the pulsed arc xenon discharges used for the optical pumping of high energy lasers. A complete explanation of these discharges requires information on the physical properties of the xenon arc plasma as a function of temperature and pressure.

The transition from a glow discharge to an arc discharge
Physica, 1936Summary The probability is studied of the transition of a glow discharge to an arc discharge when the cathode is touched by a conductor. It is found that the probability of this transition (called arcing) depends on a number of variables,. e.g. on the capacity and the potential difference between the conductor and the cathode, the current density and

Vacuum, 2000
Abstract Features of microseconds arc discharge with gap spacing of micrometers, between a cathode of thin tungsten wire with sharpened tip and an anode of stainless-steel plate, have been experimentally investigated. The experimental setup, which consists of a micro-arc torch, precise positioning mechanisms actuated by piezoelectric devices and ...

New studies of the arc discharge
Electrical Engineering, 1933The equation V = A + B/In which correctly represents all normal arc characteristics is used as the starting point for a general discussion of arc phenomena and industrial applications. Tests of this equation are applied to iron arcs in various gas atmospheres to obtain a series of values for A and B, making possible certain deductions about arc voltage

ARC Discharge in Synthesis of Fullerenes
Journal of Engineering Physics and Thermophysics, 1998For the first time, under fullerene synthesis conditions a quasiperiodic space-time structure of the arc and a correlation of plasma brightness pulsations with the change in the electrical parameters of the discharge are found, which can be attributable to superheating instability and unsteady transfer of carbon particles to the plasma.

Arc discharge sputtering of schungites
Technical Physics, 2004The schungite structure is shown to be modified in an arc discharge in an inert gas atmosphere. As a result of the direct effect of the arc discharge, some portion of the schungite material transforms locally into rhombohedral graphite. The spectral dependence of the optical transmission of the solutions of graphite soot and schungite soot in toluene ...

Moving Striations in Arc Discharge
Journal of the Physical Society of Japan, 1958In the same manner as in glow discharge, the moving striations are observed in arc discharge. From the patterns of light oscillation, a light intensity wave travelling towards the cathode is obtained. The phenomenon of the moving striations is one manifestation of the light intensity wave which occurs due to an interaction between the following two ...

13th Aerospace Sciences Meeting, 1975
A computer progrem using nonlinear RLC circuit analysis was developed to accurately model the electrical discharege performance of the Ames 1-MJ energy storage and arc-driver system. Solutions of circuit parameters are compared with experimental circuit data and related to shock speed measurements.

Progress in Energy and Combustion Science, 1999
Abstract The sliding arc discharge starts at the shortest distance between the electrodes, then moves with the gas flow at a velocity of about 10 m/s and the length l of the arc column increases together with the voltage. When the length of the gliding arc exceeds its critical value l crit , heat losses from the plasma column begin to exceed the ...

Journal of Food Safety, 2000
Scope of Deliverables: This section covers early applications of electricity to pasteurize fluids. The use of arc discharge for liquid foods is unsuitable largely because electrolysis and the formation of highly reactive chemicals occur during the discharge. More recent designs show some promise for this technology, although this should be confirmed by
