The angular distribution of bremsstrahlung gamma rays produced by fast electrons accelerated in relativistic laser-solid interaction has been studied by photoneutron activation in copper. We show that the gamma-ray beam moves from the target normal to the direction of the k(laser) vector as the scale length is increased. Similar behavior is found also in 2D particle-in-cell simulations.
CALCULATIONS OF THE GIANT-DIPOLE-RESONANCE PHOTONEUTRONS USING A COUPLED EGS4-MORSE CODE J. C. Liu, W. R. Nelson, K. R. Kase and X. S. Mao Stanford Linear Accelerator Center, P. 0. Box 4349, Stanford, CA 94309 Abstract The production and transport of the photoneutrons from the giant-dipoleresonance reaction have been implemented in a coupled EGS4-MORSE code. The total neutron yield (including b...
Simulations of photoneutron generation are presented for the anticipated experimental campaign at ELI-ALPS using under-commissioning e-SYLOS beamline. Photoneutron is a three-step process starting with creation relativistic electron beam which converted to gamma radiation, in turn generates neutrons via ?,n interaction high-Z material. Electrons accelerated energies laser wakefield acceleration...
