The plasma parameters of an RF-driven plasma microjet in different applied RF powers, different positions from the outlet nozzle, and various argon flow rates are investigated. A double Langmuir probe is designed and constructed, then, the electron temperature, ion density, and saturation currents along the microjet axis at different positions such as top, mid, end […]
AbstractThe electron-neutral collisions in the plasma become crucial with regard to the generation of THz radiation when thermal motion of the electrons is considerable. If we look at the mechanism of THz emission, this is only the movement/oscillations of the electrons which is responsible for the excitation of nonlinear current that generated the THz radiation.
