  The temperature of a dust ensemble in a dusty plasma is one of its most
fundamental properties. Here, we present experiments using the configurational
temperature as a for the temperature analysis in dusty plasmas. Using a model
of the particle interactions, the configurational temperature allows us to
determine the temperature of the dust ensemble from measurements of the
particle positions, rather than particle velocities. The basic concept will be
presented and the technique is applied to two-dimensional finite clusters as
well as three-dimensional data from an extended dust cloud. Additionally, the
configurational temperature can be used to derive the particle charge and the
screening length from a comparison with the standard kinetic temperature.
