Synchrotron radiation, pair production and longitudinal electron motion during 10-100PW laser solid interactions
C. S. Brady, C. P. Ridgers, T. D. Arber +1
At laser intensities above 1023W/cm2 the interaction of a laser with a plasma is qualitatively different to the interactions at lower intensities. In this intensity regime solid ta…
Modelling Gamma Ray Emission and Pair Production in High-Intensity Laser-Matter Interactions
C. P. Ridgers, J. G. Kirk, R. Duclous +5
In high-intensity (> 10^21W/cm^2) laser-matter interactions gamma-ray photon emission by the electrons can strongly affect the electron's dynamics and copious numbers of electron-p…
Pair plasma cushions in the hole-boring scenario
J. G. Kirk, A. R. Bell, C. P. Ridgers
Pulses from a 10 PW laser are predicted to produce large numbers of gamma-rays and electron-positron pairs on hitting a solid target. However, a pair plasma, if it accumulates in f…
Dense electron-positron plasmas and bursts of gamma-rays from laser-generated QED plasmas
C. P. Ridgers, C. S. Brady, R. Duclous +4
In simulations of a 12.5PW laser (focused intensity I = 4x10^23W/cm^2) striking a solid aluminium target 10% of the laser energy is converted to gamma-rays. A dense electron-positr…
