 note = {Detections of the pulse durations and arrival timings of relativistic electron beams are important issues
in accelerator physics. Electro-optic diagnostics on the Coulomb fields of electron beams have the
advantages of single shot and non-destructive characteristics. We present a study of introducing the
electro-optic spatial decoding technique to laser wakefield acceleration. By placing an electro-optic
crystal very close to a gas target, we discovered that the Coulomb field of the electron beam possessed a
spherical wavefront and was inconsistent with the previously widely used model. The field structure was
demonstrated by experimental measurement, analytic calculations and simulations. A temporal mapping
relationship with generality was derived in a geometry where the signals had spherical wavefronts.
This study could be helpful for the applications of electro-optic diagnostics in laser plasma acceleration
experiments.},
