Abstract

This research paper focuses on the study of Spherical Langmuir Probe I-V characteristics in Maxwellian space plasma. This work is conducted using computational techniques to create the exact plasma conditions of the experimental testing environments. The investigations address the development of a technique to model Maxwellian plasma. Three different sized Langmuir probes has been designed theoretically for ionospheric temperature 0.5eV, with the help of computational techniques; I-V traces are produced to analyze the plasma parameters. The variation of floating potential due to probe size is clearly depicted. A manifest trail in the I-V curves is the bump that occurs right after the floating potential. This feature in the transition region affects ability to determine the electron temperature, ion saturation current and plasma potential.
