Claim Text:
1. A system, comprising: a) a set of one or more electro-optic (EO) materials placed in close proximity to a design trajectory of a charged particle beam; and b) a set of one or more optical probes configured to receive a beam of electromagnetic radiation and probe a change of refractive index of the one or more EO materials resulting from passage of the charged particle from the beam due to the electro-optic effect of the charged particle's electromagnetic field; and c) a set of one or more photon detectors coupled to the one or more optical probes, wherein each photon detector in the set is configured to produce a photon signal that corresponds to the change of refractive index of a corresponding EO material of the set of one of the one or more EO materials.
