PhD Position – Optimization of laser-driven particle sources for the generation of medical radioisotopes In part-time (65%) Reference number: 26.155-1700 (m/f/d)

The GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt operates one of the world's leading accelerator facilities for fundamental research. Together with international partners, GSI is currently building FAIR (Facility for Antiproton and Ion Research), one of the largest research projects worldwide. GSI and FAIR offer the opportunity to work in an international environment within a dedicated team committed to scientific excellence. Within the framework of the research project lasEr-driven Universal Radio-isOtope Production Accelerator (EUROPA), we are seeking at the earliest date possible: PhD Position (all genders) – Optimization of laser-drive particle sources for the generation of medical radioisotopes In part-time (65%) Reference number: 26.155-1700 Project Context (EUROPA) EUROPE (for lasEr-driven Universal Radio-isOtope Production Accelerator) is a European initiative aiming to transform how medical radioisotopes are produced for cancer research and treatment. Targeted radionuclide therapy (TRT) is one of the most promising approaches in nuclear medicine, relying on artificial radioactive isotopes (ARIs) to precisely identify and destroy cancer cells. However, access to these innovative isotopes is limited: You are expensive and difficult to supply because You rely on large, centralized facilities. However, Laser-Plasma Acceleration (LPA) could offer a highly versatile source of radiation (γ-rays) and particles (ions and neutrons) across a broad energy spectrum, making it a promising approach for generating the moderate activity levels required for innovative radiopharmaceutical applications. To demonstrate this potential, EUROPA focuses on innovative pairs of theranostic artificial radioisotopes. The project aims at optimizing LPA mechanisms to enhance the yield of accelerated particles within the desired energy range. At the same time dedicated detectors are being developed to support proof-of-concept experiments for radioisotope production, which could be scaled to modern high-repetition rate medium-energy laser systems. The advertised position plays a central role in the enhancement and optimization of the respective laser-driven particle sources required for the subsequent radioisotope generation process. It focuses on the development of a laser-driven alpha source in sequence, phased, with a second focus on laser-driven electron acceleration in the self-modulated laser-wakefield acceleration regime.

Setup and execution of hydrodynamic simulations for studying the optical shaping process of the balancing targets Setup and execution of particle-in-cell simulations for studying the laser-driven particle acceleration Design and execution of experimental campaigns at the high-power laser system PHELIX for validation and benchmarking of the developed simulation models. Participation in project-related experiments at international European laser facilities Close collaboration with internal project partners (postdocs, PhD students) as well as external partners from academia and industry. Documentation of experiments, their analysis, as well as publication of the results in scientific journals and at international conferences.

Completed university degree (Master's or equivalent) in physics, ideally with a focus on laser- and / or plasma physics. Solid knowledge in at least one of the following areas: laser physics, plasma physics Basic programming skills (e.g. Python) and interest in analysis data. Experience with numerical simulation of laser-plasma interactions is an advantage. Ideally, hands-on experience on optical setups Motivation to work on both theoretical/numerical and experimental topics. Independent and structured working style with validation of own results, as well as the ability to work in an interdisciplinary team. Good command of English (written and spoken); German language skills or willingness to acquire them are an advantage.

Access to a unique experimental environment and modern research infrastructures at GSI/FAIR and other European facilities. Employment at GSI within the EUROPA project in close collaboration with national and international partners.
