Characterization of laser-driven proton beams for static and dynamic radiography
POSTER
Abstract
with other laser-driven particle/radiation species, such as X-ray photons and neutrons. We
conducted experiments at the Omega-EP laser to characterize the laser-driven proton beam
spectra and spatial source profiles using Thomson parabola and PROBIES (PROton Beam
Imager and Energy Spectrometer) for CH foil targets with different thicknesses and with/without
Compound Parabolic Concentrator (CPC) cone. Both diagnostics indicate that: (1) maximum
proton energy of >~ 70-80 MeV is achieved in thin CH flat foil targets; (2) generally, thin CH
flat foils have better performance than thicker foils or placing the foil behind a CPC cone.
Preliminary static and dynamic radiography were also conducted using these proton beams.
Quality of these radiography results will be contrasted and discussed in the context of different
characteristics of the probe proton beams.
