• Positron acceleration paper accepted in PRL

    The work “Stable positron acceleration in thin, warm, hollow plasma channels” by EPP team members Thales S and Jorge V, by EPP team alumni Diana A, and collaborators in the US (Mike Downer, Mark Hogan, Vitaly Yakimenko and Rafal Zgadzaj) was recently accepted for publication in Physical Review Letters. In this work, Thales et al. propose a novel regime for positron acceleration, which may deliver high quality positron bunches free from deleterious instabilities in experiments.

  • Les Houches school to be co-organized by EPP member Thomas G

    The next edition of the Les Houches plasma physics school will be co-organized by EPP researcher Thomas G and Mickael Grech (LULI, France) in May 2023. The school was planned to occur in 2021, but it was cancelled due to the COVID-19 pandemic.

    The Les Houches plasma physics school is typically organized every two years at Les Houches, in the beautiful Chamonix Valley in the french Alps, gathering a group of renowned lecturers in plasma physics. Space, astrophysical as well as laboratory plasmas will be considered with a special emphasis on the timely topic of plasmas under extreme conditions as found e.g. in the interior of planets, in the most violent astrophysical environments, or created using extreme-light lasers.

    EPP students and lecturers have participated in previous editions of this school in 2013, 2015, and 2019.

  • ZPIC featured in European project for optimization of HPC applications

    The joint European project Effort toward a Highly Productive Programming Environment for Heterogeneous Exascale Computing (EPEEC) has conducted a test on the effective advantages of task-based parallel programming models using ZPIC as a reference High-Performance Computing (HPC) application for kinetic plasma simulations. The results from this test show a path for alternative high-efficiency parallelization of the PIC algorithm that can be straightforwardly applied in many novel architectures, including FPGA and GPGPU based accelerators.

    Different task-based implementations of ZPIC have been developed based on the OmpSs-2 programming model and their performance was tested on two classical test plasma physics problems: laser wakefield acceleration and the Weibel instability. Some of the implementations demonstrated near-perfect scaling for 48 cores despite unbalanced conditions, an impressive result accomplished while retaining the code simplicity of task-based programming. More details of this study can be found here.

    EPEEC’s main goal is to…

  • Article by EPP researchers in PRE Spotlight

    The article “Seeded QED cascades in counter-propagating laser pulses” published in Physical Review E in 2017 by Thomas G, Marija V, Joana M, Ricardo F and Luis OS has been selected for a Physical Review E (PRE) Spotlight on Laser-created Pair Plasmas. Each PRE Spotlight represents a small selection of articles, dealing with the same research area. The article provides an exhaustive study about the growth rates of QED cascades in counter-propagating lasers. In addition to the new analytical work developed by the authors, all recent existing theoretical models for the growth rate from other authors are shown and compared to first-principles QED-PIC simulations. A discussion about the cascade’s threshold is included, based on the analytical and numerical results. The paper is available here.

  • Recent paper in PoP selected as an Editor's Pick

    A recent paper in Physics of Plasmas by EPP members Bernardo M and Jorge V and collaborators at Rochester University, USA, entitled “Laser-plasma acceleration beyond wave breaking” has been selected by the editors of Physics of Plasmas as a featured article. This paper discusses how superluminal plasma wakefields prevent wave-breaking of strongly nonlinear plasma waves in the blowout regime and thus self-injection of electrons into the plasma wake. This leads to enhanced and cleaner accelerating fields. Our finding could be an important step to further reduce the size and improve the quality of future plasma based accelerators.
