Electric Discharge in Vacuum Tubes

Types of Vacuum Tubes

Electric discharge during electrosurgery

Electric discharge utilized for electrosurgery is studied by means of a recently developed method for the diagnostics of small-size atmospheric plasma objects based on Rayleigh scattering of microwaves on the plasma volume. Evolution of the plasma parameters in the near-electrode sheaths and in the positive column is measured and analyzed. It is found that the electrosurgical system produces a ...

Gamma Ray Burst as Vacuum Discharge of Super-Schwinger Electric Fields

A theory is proposed to explain with simplicity the basic observed properties of a Gamma Ray Burst (GRB). It employs a well-known result of Schwinger, that static electric fields in excess of a critical value are unstable to pair creation, and catastrophically produces a thermal plasma at temperatures ≤ 0.5 MeV. By using observational values for the energy and volume of the source, it is shown ...

Finite Element Modeling of Compressor Discharge Tubes

Discharge tubes in hermetically sealed refrigeration compressors are often a source of fatigue failure which is not serviceable and necessitates the replacement of the compressor. The finite element method can be used to model the discharge tube to help prevent such failures and to reduce costs by optimizing the tube. This investigation considers techniques for modeling discharge tubes with fin...
