Detector Development and Data Analysis for Laser-Accelerated Ions (Id 432)
Student practical training / Bachelor theses / Master theses / Diploma theses / Student Assistant / Research Assistant
HZDR develops and operates two high-intensity lasers as drivers for plasma-based accelerators—a novel concept for compact sources that deliver ultra-short pulses of high-energy ions and electrons. We experimentally investigate plasma-based acceleration from the physical fundamentals to applications, for example, for free-electron lasers, as particle sources for radiobiological studies, or for neutron sources.
A variety of detectors are used for the characterization and optimization of plasma acceleration. The focus is on implementing and optimizing data analysis methods for existing detector technologies using new methods, including machine learning.
Focus of the Work:
- Design and application of scintillator-based tomographic detector systems
- Further development of existing algorithms and implementation of new data analysis methods (using, among other tools, PyTorch)
- Data analysis

Simulation of Spontaneous Emmission for High-Energy Laser Amplifiers (Id 427)
Student Assistant / Volunteer internship / Research Assistant
Motivation
Most lasers are based on the so-called Stimulated Emission, which releases the energy stored by absorption (in the excited laser state) through stimulated emission to the photons to be amplified. However, there are some catches: The lifetime of the excited state is finite (spontaneous emission), and the excited ions not only see the desired light of the laser but also the spontaneously emitted photons of neighboring ions. To build an efficient laser (e.g., driver for laser-induced fusion), one must have very precise knowledge of these processes. For this purpose, the software HASEonGPU, based on C++ and CUDA, was developed at HZDR, which can calculate this influence on the HZDR cluster.Tasks
- Familiarize yourself with the fundamentals of the influence of Amplified Spontaneous Emission (ASE - Amplified Spontaneous Emission).
- Familiarize yourself with the compilation and execution of HASEonGPU on a Linux cluster.
- Translate a Matlab-based script for data preparation for HASEonGPU to Python.
- Develop a workflow for conducting HASEonGPU simulations for parameter scans, parameter optimization and integration into machine learning.
- Port HASEonGPU from CUDA to Alpaka to make it executable on other GPUs and multi-core CPUs.
- Profile and optimize the C++ code to increase the throughput of simulations.

- Knowledge of working with a Linux/Unix shell
- Ability to work independently and systematically solve problems

Detection and data evaluation for laser-accelerated electrons (Id 425)
Student practical training / Bachelor theses / Master theses / Diploma theses / Student Assistant / Research Assistant
The HZDR develops and operates two high-intensity lasers as drivers for plasma-based accelerators - a novel concept for compact sources delivering ultrashort pulses of high-energy ions and electrons. We conduct experimental research into plasma-based acceleration, from the physical principles to applications, for example for free-electron lasers, as particle sources for radiobiological studies or for neutron sources.
One of the ways we gain an understanding of the processes involved in plasma acceleration is by detecting and spectrally characterizing the accelerated particles and comparing the measurement results with simulations of plasma dynamics. To this end, the detection and evaluation methods for energetic electrons in particular must be optimized.
Work plan:
- design and simulation of electron spectrometers
- construction of electron spectrometers and integration into the experimental setup
- further development of existing algorithms for data evaluation
- data analysis
