Electron-Neutral Collision Frequency Determination of Plasma Medium

Plasma medium is often referred to as the fourth state of matter, since it has properties very much different from those of the gaseous, liquid, and solid states. The simple and available plasma medium in the market is fluorescent lamp. In standard fluorescent lamps, mercury vapor pressure plays one of the key roles to define electron density. In view of the fact that, electrical conductivity of plasma depends on electron density and electron-neutral collision, the vapor pressure plays important role in determining plasma electrical conductivity too, which is important properties in determining the performance of plasma medium if they are used to radiate microwave signals. Therefore, as reported in this paper, the electron-neutral collision is estimated by conducting experiments and simulations. It was concluded from the results that the electron-neutral collision of commercially available plasma medium is 900 MHz.
