A floating potential method for measuring ion density

The method is based on an ex-trapolation to the floating potential of the saturation ion current raised to the 4/3 power. This procedure is not supported by theory but apparently works because effects neglected in the theory tend to cancel. I. INTRODUCTION AND METHODOLOGY Langmuir probe measurement of the plasma density n in the weakly ...

Density: Accuracy and Precision

Density: Accuracy and Precision Introduction: Density is a measure of a substance’s mass-to-volume ratio. For liquids and solids, density is usually expressed in units of g/mL or g/cm3; these are equivalent since 1 mL is exactly equal to 1 cm3. Density is an intensive property meaning that a substance’s density will be the same regardless of
