Abstract
Diagnostic methods are developed to measure the microparticle charge
Q
and two plasma parameters, electron temperature
T
e
, and ion density
n
i
, in the main plasma region of a dusty plasma. Using video microscopy to track microparticles yields a resonance frequency, which along with a charging model allows an estimation of
Q
and
T
e
. Only measurements of microparticle position and velocity are required, unlike other methods that use measurements of
T
e
and plasma parameters as inputs. The resonance frequency measurement can also be used with an ion drag model to estimate
n
i
. These methods are demonstrated using a single-layer dusty plasma suspension under microgravity conditions.
