Simulations of Alfven wave driving of the solar chromosphere - efficient heating and spicule launching
C. S. Brady, T. D. Arber
Two of the central problems in our understanding of the solar chromosphere are how the upper chromosphere is heated and what drives spicules. Estimates of the required chromospheri…
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…
Characteristics of magnetoacoustic sausage modes
A. R. Inglis, T. Van Doorsselaere, C. S. Brady +1
Aims: We perform an advanced study of the fast magnetoacoustic sausage oscillations of coronal loops in the context of MHD coronal seismology to establish the dependence of the sau…
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…
