Intrinsic resolution limits of monolithic organic scintillators for use in rep-rated proton imaging

Abstract Rep-rated diagnostics are a necessity for present and future laser facilities focused on the study of high-energy-density (HED) phenomena. Electromagnetic fields in HED systems are of particular interest to the community, but are inherently difficult to diagnose due to the high mass-densities involved. By utilizing high-energy protons that penetrate through dense plasmas, fields may be visualized by detecting variations in proton fluence caused by the Lorenz interaction of the protons with the field. Typical detecting media used for proton imaging are single-use and do not scale well to rep-rated operation. We propose here the use of a scintillator-based detector and characterize the energy and spatial responses to demonstrate its feasibility as a viable option for rep-rated proton imaging and other diagnostics.
