Abstract
We propose a scheme to mapping electromagnetic field structure in plasma by using a spin polarized relativistic electron beam. Especially by using Particle-in-Cell (PIC) and spin tracing simulations, we have successfully reconstructed a plasma wakefield from the spin evolution of a transmitted electron beam. Electron trajectories of the probe beam are obtained from PIC simulations, and the spin evolutions during the beam propagating through the fields are calculated by a spin tracing code. The reconstructed fields illustrate the main characters of the original fields, which demonstrates the feasibility of field detection by use of spin polarized relativistic electron beams.
