A comparison of weak-turbulence and PIC simulations of weak electron-beam plasma interaction
Heather Ratcliffe, Christopher S Brady, Mohammad B Che Rozenan +1
Quasilinear theory has long been used to treat the problem of a weak electron beam interacting with plasma and generating Langmuir waves. Its extension to weak-turbulence theory tr…
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…
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…
Dense Electron-Positron Plasmas and Ultra-Intense Bursts of Gamma-Rays from Laser-Irradiated Solids
C. P. Ridgers, C. S. Brady, R. Duclous +5
In simulations of a 10PW laser striking a solid we demonstrate the possibility of producing a pure electron-positron plasma by the same processes as those thought to operate in hig…
