The effect of electric fields on the burning velocity of various flames
When a dc, ac, or hf electric field acts across a vertical tube filled with a mixture of natural gas (CH4) or ethylene and air at 1 atm, the speed of flame propagation is shown to rise well above itsExpand
Ionization Phenomena in Gases
Ionization in Gases by Electrons in Electric Fields
Prior to the 18th century it was thought that a gas was an ideal electrical insulator, that electric charges of either sign could not be made to pass through it and that electric currents could notExpand
Excitation Processes and the Theory of the Arc Discharge
No satisfactory theory exists to account for the current transfer at the cathode of an arc the cathode material of which has a low boiling point, such as mercury or copper. Whereas thermionicExpand
An Explanation of the Tanberg Effect
WHEN an arc discharge at very low pressure passes between metal electrodes the cathode experiences a force directed away from the anode. By suspending a copper cathode on a pendulum and observing theExpand
Theory of the Double Probe at High Gas Pressure
ABSTRACT It is shown that the mean electron energy in a uniform steady plasma at high gas pressure can be obtained from the analysis of a plane double probe curve. If the motion of charges to theExpand

THERE are two interesting aspects of the distribution of a direct current flowing between soluble metal electrodes in an aqueous electrolyte confined in an insulating vessel. Theoretically theExpand
New trends in vacuum research based on ionisation phenomena
Abstract The range of pressure measurement of the McLeod gauge and the Philips ionisation gauge has been extended recently. For the measurement of ultra-high vacua only the thermionic ionisationExpand
