Role of self-generated magnetic fields in the inertial fusion ignition threshold
James D. Sadler, Christopher A. Walsh, Ye Zhou +1
Magnetic fields spontaneously grow at unstable interfaces around hot-spot asymmetries during inertial confinement fusion implosions. Although difficult to measure, theoretical cons…
Updated Magnetized Transport Coefficients: Impact on Laser-Plasmas with Self-Generated or Applied Magnetic Fields
Christopher Walsh, James Sadler, Jonathan Davies
Errors in the Epperlein & Haines [PoF (1986)] transport coefficients were recently found at low electron magnetizations, with new magnetic transport coefficients proposed simultane…
Thermomagnetic instability of plasma composition gradients
James D. Sadler, Hui Li
We show that, under Braginskii magneto-hydrodynamics, anti-parallel gradients in average ion charge state and electron temperature can be unstable to the growth of self-generated m…
Symmetric set of transport coefficients for collisional magnetized plasma
James D. Sadler, Christopher A. Walsh, Hui Li
In Braginskii extended magneto-hydrodynamics (ExMHD), applicable to collisional astrophysical and high energy density plasmas, the electric field and heat flow are described by the…
Nonlinear wakefields and electron injection in cluster plasma
Marko Mayr, Ben Spiers, Ramy Aboushelbaya +6
Laser and beam driven wakefields promise orders of magnitude increases in electric field gradients for particle accelerators for future applications. Key areas to explore include t…
Magnetization around mix jets entering inertial confinement fusion fuel
James D. Sadler, Hui Li, Brian M. Haines
Engineering features are known to cause jets of ablator material to enter the fuel hot-spot in inertial confinement fusion implosions. The Biermann battery mechanism wraps them in…
Magnetic field generation from composition gradients in inertial confinement fusion fuel
James D. Sadler, Hui Li, Kirk A. Flippo
Experimental asymmetries in fusion implosions can lead to magnetic field generation in the hot plasma core. For typical parameters, previous studies found that the magnetisation Ha…
Kinetic simulations of fusion ignition with hot-spot ablator mix
James D. Sadler, Yingchao Lu, Benjamin Spiers +9
Inertial confinement fusion fuel suffers increased X-ray radiation losses when carbon from the capsule ablator mixes into the hot-spot. Here we present one and two-dimensional ion…
Essential criteria for efficient pulse amplification via Raman and Brillouin scattering
R. M. G. M. Trines, E. P. Alves, E. Webb +14
Raman and Brillouin amplification are two schemes for amplifying and compressing short laser pulses in plasma. Analytical models have already been derived for both schemes, but the…
QED-driven laser absorption
M. C. Levy, T. G. Blackburn, N. Ratan +13
Absorption covers the physical processes which convert intense photon flux into energetic particles when a high-power laser illuminates optically-thick matter. It underpins importa…
