Understanding Langmuir probe current-voltage characteristics
I give several simple examples of model Langmuir probe current-voltage I-V characteristics that help students learn how to interpret real I-V characteristics obtained in a plasma. Students can also create their own Langmuir probe I-V characteristics using a program with the plasma density, plasma potential, electron temperature, ion temperature, and probe area as input parameters. Some examples...
متن کاملCurrent - Voltage Characteristic of a PartiallyIonized Plasma in Cylindrical
The properties of a partially ionized plasma in a long cylindrical tube subject to a uniform axial electric eld are investigated. The plasma is maintained by an external ionizing source balanced by bulk and surface recombinations. Collisions between neutrals, whose density greatly exceeds the density of charged particles, and of neutrals with ions are suuciently eeective for their velocity dist...
متن کاملDouble Langmuir probe measurement of plasma parameters in a dc glow discharge
In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...
متن کاملUse of Langmuir probes in non-Maxwellian space plasmas
Disturbance of the Maxwellian plasma may occur in the vicinity of a spacecraft due to photoemission, interactions between the spacecraft and thermospheric gases, or electron emissions from other devices on the spacecraft. Significant non-Maxwellian plasma distributions may also occur in nature as a mixture of ionospheric and magnetospheric plasmas or secondaries produced by photoionization in t...
متن کاملInfluence of O2 and N2 Concentrations on the Characteristics of Plasma in DC Cylindrical Magnetron Discharge by Langmuir Probe
Using the Langmuir probe method, the reactive plasma parameters were studied in different ratios of oxygen and nitrogen concentrations in a DC cylindrical discharge device.The plasma parameters such as plasma potential, electron density and electron temperature wereextracted from the current-voltage characteristic’s curve of Langmuir probe to find the optimum conditions for deposit the oxy...
