Characterization of laser-driven proton beams for static and dynamic radiography

POSTER

Abstract

Laser-driven proton beams can be used as probes for static and dynamics radiography together

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.
