A first principles 6D kinetic model is developed to study the earliest times of unassisted plasma breakdown in an International Thermonuclear Experimental Reactor (ITER)-scale tokamak. This is then used for a comparative study of the predicted ionisa

Publikováno v: Physica scripta 96, 055603 (2021). doi:10.1088/1402-4896/abe77f

In this paper the energy gain of attosecond electron bunches emitted during the interaction of intense, few-cycle linearly polarized lasers with nanoscale spherical clusters is determined. In this case electron bunches are emitted from the rear side

We have modeled bi-color circularly polarized harmonic generation in under-dense plasmas using a combination of PIC simulation and a nonlinear fluid model. Generalized selection rules and helicities, together with harmonic efficiencies are predicted

Relativistic attosecond electron bunch emission from few-cycle laser irradiated nanoscale droplets

Autor: Laura Di Lucchio, Paul Gibbon

Publikováno v: Physical Review Special Topics. Accelerators and Beams, Vol 18, Iss 2, p 023402 (2015)

Attosecond electron bunches produced at the surface of nanometer-scale droplets illuminated by a two-cycle laser pulse are investigated for the purpose of determining their optimal emission characteristics. Significant departures from Mie theory are
