Abstract

Proton radiography’s utilization of positively charged probing particles makes it susceptible to potential influences from electromagnetic forces generated at the target object. In this work, we investigate how the 800 MeV proton radiography system of Los Alamos National Laboratory would respond to such influences with intentions to develop proton radiography/deflectometry diagnostics capable of probing electromagnetic fields inside dynamically changing objects. To understand how the proton radiography system responds to object-generated electromagnetic fields, a series of simulations were performed, which map proton trajectories through the system. This leads to an understanding of how the radiographic images, normally dominated by multiple Coulomb scattering, would be modified. The simulations also highlight novel ways in which additional data could be collected to glean more information about electromagnetic influences within and around the target object.
