The project focused on the research and development of key components for the CosmoPort Demo System (CPDS). This included the development of customized Silicon Photomultipliers (SiPMs) designed to optimize light detection from scintillating fibers, which are crucial for tracking muon trajectories. A first production batch of these SiPM arrays was manufactured and tested, with different cell sizes and packaging options explored.
A highly efficient Data Acquisition (DAQ) system was also developed, significantly reducing power consumption and cost compared to commercial alternatives. This system ensures accurate signal capture and precise timing, essential for high-resolution muon tracking.
Furthermore, a novel fiber mat design was prototyped, demonstrating the potential to increase production speed without compromising technical specifications. This design is intended to improve the efficiency and scalability of the hodoscope system, which is responsible for detecting muons.
Algorithms for material classification and object reconstruction were also developed. Existing material classification methods were independently verified, showing high accuracy in identifying different substances. Work is ongoing to improve the simulation of the hodoscope system to enhance the training data for these algorithms.
A beta version of the graphical user interface (GUI) was created, enabling visualization and analysis of 3D data from the muon tomography system. This GUI allows for detailed examination of scanned objects, including material density filtering and cross-sectional views.
Finally, a mobile platform in the form of a trailer was designed, with a contract signed for its construction. This trailer will house the CPDS and facilitate on-site inspections at various locations.
These technical advancements contribute to the development of a robust and efficient mobile muon tomography system, with the potential to significantly improve customs inspection processes.
