Description
We present an improved electro-optic sampling technique that extends the sensitivity and temporal resolution of beam diagnostics beyond conventional limits. Through precise calibration of the detection system, we reconstruct the spatio-temporal profile of the near-field generated by a relativistic electron beam in a ZnTe crystal. This allows for accurate retrieval of the beam’s peak current with temporal resolution exceeding the nominal THz bandwidth of the electro-optic response. The method is validated at the UCLA Pegasus Laboratory, enabling single-shot detection of electron beams with charges below 100 fC.
