The spatial resolution and imaging characteristics of plastic scintillators are characterized
using laser-driven proton beams. Laser-driven proton beams typically have broad energy
spectra and are accompanied by relativistic electrons and high-energy photons, both
potentially contributing to background noise. Different types and thicknesses of Eljen
Technology scintillators are compared to determine their intrinsic point spread function.
Point-projection imaging of a mesh is used to compare the imaging resolution of the …
