Dr. Michael Bussmann (Helmholtz-Zentrum Dresden - Rossendorf)31.01.20, 10:35Laser plasma acceleration is transitioning from basic research to application and this transition is not finished. At the one side of the spectrum, new experimental techniques and facilities enable a first look on the acceleration dynamics with atomic resolution. On the other hand, simulations of the fundamental process are reaching predictive capabilities in both laser-driven elctron and...Go to contribution page

Prof. Ricardo Fonseca (Instituto Superior Técnico)31.01.20, 11:00TalkThe OSIRIS [1] Electromagnetic particle-in-cell (EM-PIC) code is widely used in the numerical modeling of many kinetic plasma laboratory and astrophysical scenarios. Working at the most fundamental microscopic level and needing to resolve the smallest spatial and temporal scales, these are the most compute-intensive models in plasma physics, requiring efficient use of large scale HPC systems....Go to contribution page

Frau Viktoria Pauw (LMU)31.01.20, 11:25We report on a 3D simiulation study of relativistic short laser pulses (10< a0 <120, 20-150 fs FWHM) interacting with isolated targets of micrometer size. Topic of the study is the emission of fast protons from targets representing hydrogen gas clusters or plastic spheres. Different densities from undercritical so solid conditions, show distinct acceleration mechanisms. We consider the...Go to contribution page

Prof. Bhuvanesh Ramakrishna (IIT Hyderabad)31.01.20, 11:50We have investigated the generation of dense electron-positron pairs and intense photonray bursts in the laser plasma interaction using quantum electrodynamics (QED) effects included in particle-in-cell (PIC) simulations. Linearly polarized laser pulses were used to irradiate a thin foil (1 μm) with an intensity of 4*1023 W/cm2. A scan of targets with varying Z (Al, Cu and Au) is...Go to contribution page
