The design and performance of an asymmetrical nozzle in Laser Wake Field electron accelerationThe design and performance of an asymmetrical nozzle in Laser Wake Field electron acceleration Πλήρης Δημοσίευση σε Συνέδριο Conference Full Paper 2025-02-132022enLaser Wakefield is a method for the acceleration of electrons up to the GeV level, with applications of great importance. Experimentally is realized by focusing an ultra-intense (I>1018 W/cm2), ultra-short (t~50 fs) laser pulse on an under-dense target. The parameters that interplay and lead to the tunability of the acceleration process are the laser pulse characteristics (e.g energy, pulse duration) as well as the gas density profile. We are working on the development of non-symmetric nozzles by conducting 3D computational Fluid Dynamic (CFD) simulations. Previously, we have studied conical nozzles, which were 3D printed and used in our experiments. In this work, we examine advanced, non-symmetric nozzle designs which are also 3D printed and tested.This work is part of the doctoral thesis of G. Andrianaki. The implementation of the doctoral thesis was co-financed by Greece and the European Union (European Social Fund-ESF) through the Operational Programme «Human Resources Development, Education and Lifelong Learning» in the context of the Act “Enhancing Human Resources Research Potential by undertaking a Doctoral Research” Sub-action 2: IKY Scholarship Programme for PhD candidates in the Greek Universities. This work has been carried out within the framework of the EUROfusion Consortium, funded by the European Union via the Euratom Research and Training Programme (Grant Agreement No 101052200 — EUROfusion).http://creativecommons.org/licenses/by/4.0/48th European Physical Society Conference on Plasma PhysicsProceedings of the 48th European Physical Society Conference on Plasma Physics Andrianaki Georgia Ανδριανακη Γεωργια Grigoriadis Anastasios Tazes Ioannis Fitilis Ioannis Dimitriou Vasilis Benis Emmanouil Nikolos Ioannis Νικολος Ιωαννης Papadogiannis Nektarios Tatarakis, Michael, 19..- European Physical Society Laser Wakefield method Laser pulse characteristics Gas density profile 3D computational Fluid Dynamic (CFD) simulations
