Particle charge determination from configurational temperature — •Michael Himpel and Andre Melzer — Institute of Physics, Greifswald University

The configurational temperature can be used to determine the temperature of a particle crystal from its positions rather than its velocities. This method has been found to yield the same results as the kinetic temperature measured with particle velocities. If both, the positions as well as the velocities, are measured with reasonable accuracy it is possible to extract the underlying particle charge. This poster will show the concept of the configurational temperature and present the application to dusty plasma experiments with the possibility to determine the individual charges of the particles in a two-dimensional cluster.
