Measurements of helicon wave propagation and Ar II emission
Wavemagnetic field, optical and Langmuir probemeasurements are carried out to examine fast and thermal electron contributions to plasma ionization in a helicon plasmasource. For the optical measurements, an Ar II line (443 nm) with a particularly short lifetime (7 ns) is chosen to resolve the excitation rate within a radio frequency period (73.7 ns). Information is then obtained regarding the acceleration processes and their action on the electron distribution that caused the excitation....[Show more]
