Measuring Propagation Speed of Coulomb Fields

To summarize our finding in few words, one might say that the data
do not agree with the common interpretation of the Lienard-Weichert
potential for uniformly moving charges, while seem to support the idea of
a Coulomb field carried rigidly by the electron beam.

We would welcome any interpretation, different from the Feynman
conjecture or the instataneous propagation, that will help understanding
the time/space evolution of the electric field we measure.
