Postdoctoral Researcher (all genders) for Adaptive Laser Architecture Instrumentation

GSI Helmholtz Centre for Heavy Ion Research

The GSI Helmholtz Centre for Heavy Ion Research in Darmstadt operates one of the world’s leading particle accelerator facilities for scientific research. In international collaboration, the new accelerator facility FAIR – Facility for Antiproton and Ion Research is currently under construction—one of the largest and most ambitious research projects worldwide. GSI and FAIR provide the opportunity to work in a highly international environment with a team of dedicated professionals committed to advancing science at the highest international level. Within the research project Adaptive Laser Architecture Development and INtegration (ALADIN), we are looking to fill the following position as soon as possible: Postdoctoral Researcher (all genders) for Adaptive Laser Architecture Instrumentation Posting-ID.: 26.161-1701 Project Context (ALADIN & PHELIX)Future Inertial Confinement Fusion (ICF) energy facilities will require laser systems of unprecedented stability, capable of synchronizing hundreds of high-power beamlines. The ALADIN project introduces a systemic control approach known as the Adaptive Laser Architecture (ALA), which integrates real-time feedback, automation, and advanced diagnostics across the entire laser system chain – from the pulse source to the target.In the work package LAOTSE (Laser Adaptive Optics Testbed for Stabilization Experiments), we continously develop and operate an experimental platform that emulates real-world laser dynamics for exploring cutting edge laser-beam control strategies in hard- and software. The long-term goal is to provide a clear beam control strategy with feasible software solutions for future laser fusion power plants. Your responsibilities:

Design and conduction of your own experiments for novel beam control systems, specifically for applications in future fusion power plants
Extension, operation and maintenance of an optical testbench for adaptive optics
Integration, testing and validation of control concepts from collaborations
Technology transfer to fusion startup companies

Your Profile:Core qualifications

Doctorate (PhD) in physics, engineering, optics, or a related field
Experience with building complex optical setups in experimental environments
Ability to work independently on scientific tasks, along with strong team and communication skills
Excellent German and English language skills, both spoken and written

Desirable experience

Programming knowledge in Python
Familiarity with TANGO Controls, EPICS, Karabo or other SCADA like systems
Exposure to high-throughput, real-time, or data-intensive systems
Participation in open-source or collaborative software projects

Personal qualities

Independent, structured, and solution-oriented way of working
Enjoyment of dynamic development and shaping architectures over the long term
Comfortable working with incomplete specifications and refining them together with domain experts
Strong communication and teamwork skills across disciplines
Motivation to help build a lasting beam control foundation for future fusion-scale laser systems
We Offer:
Employment at GSI conducting research within the ALADIN project
Research at the interface of fundamental and applied laser physics
Opportunity to lead an experimental infrastructure of international relevance for fusion energy
Involvement in an innovation-driven, dynamic project within a committed research team
Publication of research results in renowned peer-reviewed journals and presenting findings at international conferences
Career development and training opportunities in an excellent scientific environment
