Theoretical Study of Spherical Langmuir Probe in Maxwellian Plasma

My research is entitled ¿THEORETICAL STUDY OF SPHERICAL LANGMUIR PROBE IN MAXWELLIAN PLASMA¿. During my academic years, I was doing the research on Langmuir Probe as a key plasma diagnostic used by scientists fascinated in plasma characterization to measure the internal parameters of the bulk of the plasma. Langmuir Probes have been installed on satellites and sounding rockets to observe the general characteristics of thermal plasma in the ionosphere for more than five decades. Because of its simplicity and convenience, the Langmuir probe is one of the most frequently installed scientific instruments on spacecraft. My Master Degree dissertation explores the theoretical study of Spherical Langmuir Probe I-V Characteristics. A method has been developed and used to obtain theoretical predictions of the current collected from a collision less, Maxwellian plasma by an electrically conducting Langmuir probe having Spherical symmetry. The probe characteristic, or functional relation between current and probe potential, has been determined. The effect of electron temperature on the Electron Energy Distribution Function (EEDF) was also scrutinized.
