Radiation detector technologies require detailed modeling and optimization to achieve high performance, reliability, and application-specific functionality. At NÜRDAM, comprehensive simulation studies are conducted to understand detector physics, optimize geometries, and predict system responses under various radiation environments.
Simulation activities at NÜRDAM are structured according to different detector classes and physical processes, using state-of-the-art computational tools:
For gas-filled and micro-pattern detectors, detailed microscopic and macroscopic simulations are carried out to model electron transport, avalanche formation, and signal development. Tools such as Garfield++ and Magboltz are used to calculate electron drift properties, diffusion, gas gain, and charge multiplication processes in different gas mixtures and electric field configurations.
For semiconductor-based detectors, device-level simulations are performed to analyze electric field distributions, charge transport, and signal formation mechanisms. Technology Computer-Aided Design (TCAD) tools are employed to simulate doping profiles, carrier dynamics, and the impact of device geometry on detector performance.
Monte Carlo-based simulation frameworks such as Geant4 and FLUKA are used to model radiation–matter interactions, energy deposition, particle transport, and detector response under realistic experimental conditions. These tools enable the evaluation of detection efficiency, shielding performance, and system optimization for different radiation sources and energies.
At NÜRDAM, simulation studies are tightly integrated with experimental work and detector development activities. The center focuses on:
By combining advanced simulation tools with experimental capabilities, NÜRDAM aims to accelerate the development of next-generation radiation detection technologies and strengthen its position in international research collaborations.
