| Understanding
how ions move in a plasma is crucial to understanding overall plasma behavior
and properties. One powerful diagnostic technique is Laser Induced
Fluorescence (LIF), which makes ions glow according to their velocity.
Observing ion movement in the field of a wave in a non-perturbative manner
is necessary in order to obtain useful results. Because the plasma
used in these experiments was large (18 m long and 0.75 m in diameter),
a fiber optic probe could be used to spatially resolve the LIF signal.
Two probes were built and subsequently tested inside the plasma.
These proof-of-principle expeirments indicate that fiber optic probes can
be used to pinpoint ion motion and gain a better understanding of overall
plasma behavior.
